Hi everyone. I'm John C. Morley, The host of the JMOR Tech Talk Show and Inspirations for Your Life.
John C. Morley: (01:02)
Hey guys, it is John C. Morley here, serial entrepreneur. Welcome to the JMOR Tech Talk show. I can't believe, ladies and gentlemen, that we are in, yeah, the first Friday of December. I mean, that is really cool. Holidays are just around the corner. I know I've got like nine or 10 holiday parties, and it's like, where'd all this come from? Right? I remember when it was just Halloween or even when it was just starting to be the end of June, right? And it just kind of flew by. We got another great show for you guys tonight, so I know you're really going to appreciate this. So let's get right into it, right? We got a lot of good stuff. The first thing is the UTS student and his Alt-Bionics. So what is this all about? Well, it was roughly about three years ago, and it was just a little small school project to do a proof of concept. He actually got the second-place winner at the University Showcase contest. Still, it grabbed headlines as far away as the United Kingdom, and for their senior project at UTSA, Ryan Saavedra and three classmates had built a robotic prosthetic hand for less than $700.
John C. Morley: (02:26)
Now, that's a fraction of what many prosthetics like it on the market cost today. Their 3D printed model offering artificial intelligence-enhanced biotic prosthetics at an affordable price dangled the prospect of upheaval in a multi-billion-dollar industry. And Saavedra said, what's next? And I'll quote what he said; I had absolutely no idea. And then he said, I was an undergrad with no prior experience of building a company or commercializing a medical device. In fact, he had no plans to do so. Today Alt-bionics, the start-up Saavedra founded, is on a steady path to carry his concept to market. It's currently in talks to begin its first small-scale clinical trial venture. And it's gaining a lot of traction and attention from local investor groups and business observers far beyond San Antonio's little knit of the robotic scene area. And manufacturers from Poland and other clinicians in South Africa say they want to work with Alt-bionics. This is kind of amazing. So Saavedra took his concept beyond a school project, as he said. Still, these new segments reached a friend who asked if her cousin, an army ranger with multiple amputations from a tour in Afghanistan, could try out the model his team had created.
John C. Morley: (03:59)
Saavedra said, sure, and the veteran quickly put it on, and they programmed the hand to make a rude gesture. And Saavedra said the man was absolutely thrilled. So, and I quote, his family asked me What's next? And that question is a lot different coming from someone who these devices can help. Close quote, he said. Now Saavedra, you know, really was passionate about just doing this for, you know, his school project and most responding to a TikTok video clip he posted, showing a montage of the prosthetic development that currently has more than 18 million views on the app. Saavedra said he films just about everything he does. I think that's pretty amazing. And so we might be seeing disruption in the industry but in a good way. So while many devices with similar functionality typically cost tens of thousands of dollars, Alt-Bionics is pushing for a price point.
John C. Morley: (05:01)
Get this, ladies and gentlemen, for $3,500. Now, the Alt-bionics hand allows you to control it through sensors that direct and allow it to detect electric activity in other muscle groups, such as the forearms or shoulders. And AI helps guide the hand into various poses, but I think this is really remarkable. You know, how they did this? And just not too long ago, Alt-bionics saw $200,000 in a pre-seed funding round, and it collected 283,000. Kudos, guys. Really kudos to you guys. And so I think this is pretty amazing, and this proves that you can do anything if you believe in yourself. So you know, bionics prosthetics and just kind of using what's going on, I think, is pretty cool because a lot of people don't understand, like I said, what is next? And so I think having medical devices at a lot cheaper of a cost, they're going to be more reliable, more scalable, and have a lot more applications that we don't even know are going to be about today.
John C. Morley: (06:15)
All right, let's jump into our next topic. Our next topic comes to us from South Dakota. So South Dakota bans TikTok usage on government devices. What the heck is this all about? Well, the South Dakota governor bans state employees from using TikTok on government devices. And so south Dakota's governor signed an executive order not too long ago banning state agencies, employees and contractors from accessing TikTok on government devices, citing and I quote,” the growing national security threat by the Chinese owned social media platform, South Dakota will have no part in the intelligence gathering operations of nations who hate US.” Governor Christie Noem said in a recent press release quote the Chinese Communist Party uses information that it gathers on TikTok to manipulate the American people, and they gather data from the devices that access the platform close quote.
John C. Morley: (07:18)
And the order went into effect immediately. So it's unclear if many or any state employees were actively using TikTok on state-owned devices. But with this move, Noam is the latest lawmaker to urge tougher actions against popular short-form video apps, potentially scoring some political points and maybe some pushback. So they're not just trying to do this there, but he's hoping to take this movement across the entire United States because, you know, we really don't know what's up TikTok's sleeve. And if you had to ask me, what is TikTok doing with the data it captures? And I have to say it collects biometric data, including your face and voiceprint. It can also use and predict your age, gender, and interest based on your activity. The app also accesses information on your device's clipboard, including text, images, and video.
John C. Morley: (08:19)
So, TikTok was accused back in July of aggressive data harvesting. Is your information at risk users of the video app has been warned about its data practices and links to China? Can you keep your details safe? So I think this is panicking a lot of people, and really what's going on right now is they're trying to figure out what they can do to mitigate damages. Because, you know, we really don't know where the damages are coming from and who's directly responsible for them? I think that's number one. And I believe that TikTok has some issues. So, will TikTok be more regulated by the US? It's a global giant, okay. And while experts in lawmakers agree more regulation is needed, there's a lot of disagreement about how the regulatory scrutiny of TikTok can take place. Is TikTok’s ban in the United States possible, according to Forbes?
John C. Morley: (09:26)
Well, you know, anything is possible, but is it probable? I think that's really the question. Is it probable? And I think what we're going to find, you know, this is not the first time that bite dance, which is the name of the company that developed TikTok, has faced a ban on its social media platform, but rather the most recent in a long line of suits. So the question is, have they done anything yet? How likely is the ban on TikTok in the US? Well, an all-out ban on TikTok for the US. It's possible. It's not likely, but it has happened in India, and a lot of water would have to go under the bridge for it to happen anytime soon. So I think a lot's going on. There are definitely investigations in the Biden administration for ongoing results, but they've yet to be reported.
John C. Morley: (10:21)
And the Treasury Department's Committee on foreign investment in the United States, the CFIUS is still in talks with TikTok to try to create a security deal; bottom line, regardless of whether TikTok is dangerous for the average user, the situation raises critical questions about regulating data, privacy, security, and digital trade in the increasingly very serious interconnected global world. So the question is, are you at risk? Well, I think you've gotta be careful what information you share when you share it and who you share it with, and know that when you put something on social media, think about the fact that it's probably not safe. I said, probably not safe. What I really should be telling you is it's not safe. And you know, I think a lot of people are saying, oh, you know, you're making such a big deal of this, but, you know, I think we need to make a big deal because if we don't make a big deal of it. Something happens, like we have extortion, or we have some monopoly, or we have some type of takeover of some public utility, this could be a serious, serious problem.
John C. Morley: (11:31)
So we're definitely going to keep an eye out, but I just want to say kudos to South Dakota for really stepping up to the plate and doing something that I think a lot of other people should have done. And in response to the report, TikTok previously said, and I quote, it has constantly maintained that our engineers in locations outside of the US, including China, can be granted access to US user data on an as-need basis under those strict controls. So TikTok executives testified before a Senate panel last year if your member that doesn't share information with the Chinese government and that a USB ban security team decides, actually the base ban security team decides who can access US data from China, I don't know. And a quote from South Dakota, quoting, because of our serious duty to protect the private data of our South Dakota citizens, we must take action immediately. Noam said, I hope other states will follow South Dakota's lead, and Congress should also take broader actions. I think they're on the right track, and they haven't done enough that will cause somebody an issue, but they really have. It's just they haven't shown their cards. So we're going to keep an eye on this, ladies and gentlemen. We're definitely going to keep an eye on it. So security is becoming more and more of an issue no matter where you go or who you talk to. When I say a problem, it's definitely a problem. And if we don't embrace right now, if we don't unite, if we don't figure out what's going on, then there could be a serious, serious problem. And I'm not talking about a problem that is going to stop the world.
John C. Morley: (13:20)
I'm talking about a problem that's going to exploit people's data that's going to basically take your information in the US. Information that could compromise the security of US operations in protecting its citizens and in its naval and civil and other types of defence plants that could be militarily related, that could be weapons that could be just tactile approaches they use. It could also be our creative use for trying to combat cyber fraud. Now, I know this sounds really crazy, but you know, the truth of the matter is it's not. And more people are going to wake up when they start to see what happened. So the big question I have for you is, when will people wake up about the security problem with TikTok? When? The US military banned its members from using TikTok on government devices in late 2019 and early twenties, as did the transportation association.
John C. Morley: (14:39)
John C. Morley: (16:00)
I don't know if I really like that. Can TikTok access your camera? In summary, the permissions allow TikTok to access the camera and take pictures of video, the microphone and record sound, the device’s wifi connection and the full contact list in the device. So I believe this is only if you granted access, but the thing is, are they doing anything with our data? I mean, are they, and the question is, is TikTok spilling US data? Is it? TikTok has rejected the internet 2.0 report as a baseless TikTok spokesperson said, and I quote, the TikTok app is not unique in the amount of information it collects. We collect information that users choose to provide to us and information that helps the app function, operate securely and improve the user experience. That's a big load of BS, and you know that. Is TikTok stealing our information?
John C. Morley: (17:09)
I have to say, I don't think they're directly doing it intentionally, but I don't think they're trying to safeguard it either. So we're going to have to see what happens with TikTok. But I know one thing's for sure. We gotta be careful. We definitely gotta be careful. And Mr Musk, Elon Musk, yes, the European Union chief, warns Twitter they must comply with Europe's platform rules. But what the heck are Europe's platform rules? According to CNN Business, Washington recently reported that a top European Union official had warned Elon Musk about this. And Twitter has, and I quote, a huge work ahead, close quote, to meet its obligations under the Digital Services Act. We talked about this before. And so Europe's new platform regulation said that according to a theory, Breton, the AEUs Digital Chief, in a readout of his meeting with Musk, you know it's a problem. And I want to quote that Twitter will have to implement a transparent user policy significantly reinforcing content moderation and protecting freedom of speech, tackling disinformation with resolve and limiting targeted advertising. Close quote, Brent said in a statement, and I quote, all this requires sufficient AI and human resources, both in volumes and skills. And I look forward to progress in all these areas, and we will come to assess Twitter's readiness on-site. Close quote. Hmm.
John C. Morley: (18:47)
So during a recent meeting, Musk did agree to the EOS official's stress test, the social media platform for compliance with the DSA early next year. And Brent added that the testing, performed at Twitter's headquarters in early 2023, will provide ample opportunity for Twitter to make changes to meet illegal deadlines and prepare for an independent audit of the company's practices. This is what Breton's office had added. So I think right now, Elon's hands are really being tied, and he doesn't really know what's going on, but he knows that if he doesn't follow this, he's going to be in some serious trouble,
So I think we've gotta understand. First of all, the question is, what is Elon doing with Twitter? Okay, is it going? I would say he's spending all this money he's doing. I do not know; I don't know. I know that he wouldn't spend all this money and probably just throw it down the tubes. It's going to be an interesting, interesting battle. I'm talking about a really interesting battle because I know he could get hit with many fines. I'm not just talking about a few thousand dollars; I'm talking millions or trillions. So we're going to have to see what's going on. And the EU scrutiny could push Musk's Twitter to face additional pressure at home. And so it's going to be interesting because I don’t know if you know this, but Musk's acquisition of Twitter, Twitter included financing from a Saudi Prince. Yellen had said that it could be appropriate for the Committee on Foreign Investment in the United States, the CFIUS, to review Musk's Twitter takeover. This is getting like really out of hand. And the question I still want to ask is, why did Elon Musk buy Twitter? Why?
John C. Morley: (21:25)
What are his plans? They say the real reason he bought it was payments. Elon Musk took over as the CEO of Twitter and spent most of his day on the social media platform, but again, we're not getting the truth yet. Okay? Musk, of course, is part of PayPal's overseas gangster groups. And in the late nineties, it went on to become billionaires. Now, payments are in Musk's blood from day one. One of his first companies was a payment business called X Dash, a name, and he resurrected a mysterious Twitter product, claiming it would reach 104 million users by 2028. So he has been trying to interrupt the automating clearinghouse his whole career.
John C. Morley: (22:35)
He's referring to the money transfer network run by banks and Musk's Twitter play as the reincarnation of which sought to provide crypto wallets to Facebook. I just see this being something that could be a problem. Musk ran into a big problem in 1999 with PayPal. The company was in a position to disrupt the payments business because of new technology, the internet, and the maverick attitude of its executive team. Fast forward to the Twitter acquisition, and it's clear he wants to do the same thing all over again. And we're talking about FTX, Bitcoin, visa, Ethereum, and Coinbase. I think what's going to happen is he is going to change the way people think about crypto.
John C. Morley: (23:34)
And I can't say I trust what he's doing. I really can't. So I'm just going to tell you guys, caution, caution, caution, caution, caution, caution. All right, so how many of you guys like video cards? Well, video cards are pretty cool. But in the same breath, they're causing some issues. Who am I talking about specifically? NVIDIA's cables melting are NVIDIA's problems, says the PCI standards body. So you might be saying to me, John, who the heck is, who is the PCI standards body? Who is that? So it's actually the PCI Standards Council, PCI SSC. It's a global forum that brings together payments industry stakeholders to develop and drive the adoption of data security standards. But we're talking about the standard here, which can get a little confusing.
John C. Morley: (24:43)
It's the PCI standards body. So the PCI standards body is a real concern. And so the question is, what the heck happened with all this going on? Well, NVIDIA's cable's melting. They're saying our NVIDIA's problem, but what happened? They're saying that the cable wasn't, and the connector wasn't plugged in all the way to the video card. And so, if it was a user error, manufacturers should have had a way to mitigate this so that it didn't happen. So we all know video and tech watchdog gamers, Nexus with the NVIDIA RTX 4090 card and the 12-volt power cable basically started smoking and melting. And it's because they didn't plug it in all the way. But the PCI sig standards body is now suggesting that NVIDIA partners should have accounted for that. So what I want to share with you is just PCI compliance, which is credit cards, but that's not the standard I'm talking about. I'm talking about a different standard. So this is why this can get a little confusing. I'm referring to the PCI sig standards. So the PCI sig standards are not the same for the one that processes credit cards and payments. That's why I wanted to bring this up with you guys. It's the Peripheral Component Interconnect special interest group, an electronics industry consortium responsible for specifying the peripheral component interconnects PCI, PCI-X, PCI Express, and PCI-E computer buses. It's based in Beaverton, Oregon.
John C. Morley: (26:30)
My question is, what the heck are they doing Now? GPU manufacturers, I think, need to just get on board and start testing things and making sure that when things get done in an improper manner, like cables shouldn't be able to be plugged into the wrong connector. They do this on the motherboard, so you can only plug in a certain way. Definitely do that, but also make it so that if the connector is not in all the way, maybe it doesn't make a connection if they can't figure out a way to block the logic so that it doesn't actually connect the connector unless it's all the way seating. But I think they should have had some type of a watchdog to take care of this. So the PCI sig created the 12-volt horsepower WR standard, and all the PCI express standards for the matter.
John C. Morley: (27:16)
And there were some good reasons, yeah, I might want to send this now. And for one thing, they're hoping the new connector will become the standard for PCI-E 5.0 graphics cards. Now, that may not happen because NVIDIA's melting power connectors have become a safety issue. In a tweet, AMD's gaming market director Sasa Markovik suggested the 16-pin connector was a fire hazard. And I quote, stay safe this holiday season, he wrote along a picture of two old eight-pin connectors that an M D includes on its latest graphics card, the RX 7,900.
John C. Morley: (28:02)
So the bottom line is something needs to be done, but you gotta make sure you plug it in. But if you've got people building PCs and don't know what they're doing, you gotta realize that this does fall back on the manufacturer. That's number one. But that doesn't say that it dismisses the homeowner or the business owner. I think it should be basically what I call idiot-proof. You shouldn't be able to cause a fire. I mean, you just shouldn't be able to do it, right? Okay, if there's only one way to plug your plug into an outlet, and you can't plug it in the other way, then that's it, right? You can't plug it in the other way. The one plug is bigger, the polar wires, the other plug is some more, you can't plug it in the other way. If there's one way to put in a USB cable and you can't reverse it, there's one way. Certain cables you can put in two ways, right? So I think we really have to go back to responsibility. But before I dive back in on this, who is really responsible for the NVIDIA fires?
John C. Morley: (29:16)
Who is really responsible? That's just the question I want to ask you. So back around the 16th of November, the RTX owner hit NVIDIA with a lawsuit over melting a 16-pin connector.
John C. Morley: (29:44)
So one GForce RTX 4090 had taken its fight with Nvidia to the courtroom. And according to Justia, Lucas Genova recently filed a class action lawsuit against Nvidia over the 16-pin power adapter meltdown. The lawsuit states that Genova is suing the video for unjust enrichment, breach of warranty fraud, and violations of New York's general business law. Ah, I mean, crazy. The complaint states that Plaintiff purchased a GForce RTX 4090 from Best Buy for $5099.99, and he reportedly experienced the installation of the computer components like the graphics card. He installed the graphics card following the best practices. After installation, Genova eventually discovered that his 16-pin power adapter had melted. So the lawsuit says that, and I quote, thus, the Plaintiff and the class members have been hit with a costly double whammy, a premium purchase price of the 5099 for a dangerous product that should not have been sold in its current state.
John C. Morley: (31:00)
And the docket references user feedback that's been on Reddit and all these other things. But at this time, the 26 GForce RTX 4090 owners have come forward, sharing similar experiences with a 16-pin power adapter melting and sometimes damaging the 16-pin power connector on the graphics card. NVidia is still investigating the problem with the 16-pin power adapter, and the chip maker recently came forward saying that it didn't have any further details to share. However, Nvidia and its AIB partners have committed to providing some fast responses to RMAs for affected owners big deal.
John C. Morley: (31:43)
So you might be saying to me, what is the Nvidia 16-pin adapter? Well, I guess the best way to explain this to you guys is to let people use their existing power supplies and hook up multiple eight-pin connectors to the 16-pin connectors. So again, the adapter lets people use their existing power supplies and hook up multiple eight-pin connectors to the six-pin connector. So I think this is just a case of somebody who didn't test this properly. And so when we think about this and how this was designed. This was very, very poor. I mean, very poor design, okay? But there wasn't enough testing to even let this go down. So the question people ask me, John, what is the difference?
John C. Morley: (33:02)
You know, do all video cards have a 16-pin adapter? So Nvidia had the 16-pin connector. They have a six-pin GPU, and the question is, can you, can six-pin GPUs run eight pins? No, the GPU has eight pins, and it will expect an eight-pin plug. You can, however, use an adapter like the one shown in a lot of manuals to turn your six-pin power into an eight-pin power. But if you do this, you're sucking more power from the six-pin rail than necessarily designed to support. And yeah, you could have a fire issue. Do all GPUs have eight-pin connectors? If the GPU requires more than 150 watts, it will come with an eight-pin connector or two six-pin connectors. Again, the GPU will come with an eight-pin connector, okay? Or two six-pin connectors.
John C. Morley: (34:18)
Pretty easy, right? And so the most power-hungry graphics cards come with a six-pin and an eight-pin connector. But the question is, how did this, how, how did NVIDIA's RTX 4090 ever get allowed on the market? How? I think somebody skips some steps. I think they skip some steps. And the question is, what is Nvidia doing about this graphic card fire? They say they're taking a lot of steps. What steps exactly? Well, the affected cards seem to be primarily custom versions prepared by NVIDIA's partners. And the companies requested that all the cards are sent directly to the headquarters for investigation. So they claim it wasn't NVIDIA's direct fault.
John C. Morley: (35:55)
I don't know. I really don't believe them. And according to the e-card NVidia they got in touch with the labs of its ad in board partners recently, and the company requested that all the damaged RTX 4090 s sent it immediately to headquarters. But it's unclear whether this refers to manufacturers' headquarters or to NVidia itself. So that's a little bit of a question. And so far, all signs right now are seeming to lead back to an improper connection that can increase the temperatures to a point where the cable and the power connectors, yes, ignite on fire and melt. So this is caused by bending the 16-pin cable during the installation, which in all fairness, is hard to avoid since the GPU is so big. So again, it appears to be due to bending the 16-pin cable during the installation. You have to be really careful. And many PC cases simply don't have room to accommodate the card and the cable without bending it.
John C. Morley: (37:12)
The problem is really serious. And I think, you know, we're just going to have to see what they're going to do. Are they going to fix it? Are they going to hide? I don't know. But all I know is that a standard has to be set. And I think this should have gone back to PCI sig. And I also think that this should have gone through UL Labs before this was ever allowed to be solved. And this is just my personal opinion. I think they were just too fast to run to the market. I mean, if I had to be honest with you, that's the truth. I think they were just too fast to get to the market. All right, we have one more story to cover, which is pretty hot. NVidia chips power the new electric tractor robots. So a California-based start-up, Monarch tractor, is delivering its first MK dash V Smart tractor to perform farming tasks without a driver.
John C. Morley: (38:15)
How cool is that? So the Monarch Tractor is a smart electronic tractor and is the first AI-powered farming vehicle. The NK vs are rolling off the production line in Livermore, California and this start-up’s first product, and it uses in NVidia Jetson AI platform to perform agricultural tasks with or without a driver behind the wheel. Now, I want to quote what they said that NVidia Jetson enables the MK dash V to run low latency real-time AI applications while at the same time conserving energy for longer battery life and extended run times, said Monarch tractor Ceo Pravin Panmetza. So each MK dash V uses six of the Jetson Xavier NX systems on modules that enable them to navigate fields using only cameras. And it's crucial for safety since the agriculture environments may not have GP PS signals, and the visual environment is taken in by two 3D cameras plus six standard ones.
John C. Morley: (39:22)
So I think that's pretty cool how they, you know, how they've designed this and what they're doing. According to NVidia and Monarch, the tractor collects and analyses crop data daily and can process data from current and next-generation implementations that are equipped with sensors and imaging. And the data can be used for real-time implementation adjustments, long-term yield adjustments, current growth stages, and other plant and crop health metrics. The company started in 2018, the same year that NVidia launched its Jetson Xavier AI computer and the Isaac developer platform that helps companies develop and train autonomous robots. So I think this is really cool. We're going to have to see what's going on with this, and you know, what's going to happen. But I know that more people are getting excited about things becoming AI. I mean, you probably remember Roomba, right? And, the question you might be asking today is, who owns iRobot? Who owns iRobot right now? What do you think owns iRobot? So it's an American technology company that designs and builds consumer robots. So iRobot entered into a merger agreement to acquire iRobot on September 9th, 2022.
John C. Morley: (40:55)
So this is interesting. Now, you might say to me, why did Amazon buy iRobot? It's about increasing their portfolio and strengthening it. So they'd have cross-activity network effects of consumers of over 300 million smart devices in the home, and they'd be able to allow the system to gain access into people's homes for other types of data and systems that they could sell. So that's the short reason iRobot is this extension to Amazon's existing home products like Ring, Alexa and Smart Home systems. And so they believe that this would help, and it would also be part of something that would allow them to gain useful data that they could use for other products. So I think that's really the reason. And so, you know, AI is definitely pretty cool. The question is, what device or what robot is next for AI?
John C. Morley: (42:10)
I bet, I bet that's a question. I know what a lot of you are saying. AI robots are definitely becoming more popular, okay? We know from some of our previous shows that artificial intelligence can basically operate the sensors on these robots to such a precise degree that they could pick up something as simple as and as fragile as a crystal. And yet they could pick up something as hard as a hammer or pliers and be able to squeeze that with thousands of pounds of pressure. Pretty amazing that they're able to get a benchmark and then calibrator, what I like to say, dial that in so that it gives the exact effect that they're looking for. Ladies and gentlemen, I'm John C. Morley, a serial entrepreneur. It's been a privilege; it's been a pleasure. It has been an amazing honour to be with you on the first JOR Tech Talk show of December.
