Future Mars rover?
Turns out the future does have flying cars

Question shouldn't be whether we should allow autonomous cars, but how long we continue to allow humans to drive

I completely agree with this take related to the “AI will create viruses that will kill us all” BS. But let me add my few cents, because I am really really angry! I worked with one of the deadliest viruses in history, HIV, for two decades. I was one of the early scientists to engineer it, and engineered versions of HIV are now helping cancer patients. I understand the immune system that defends us against viruses extremely deeply. I have worked in high security biohazard labs. I don’t have a PhD in AI, but I have been involved with AI since the early 90s and have been all in on AI for years. People claiming that you can just make a virus in your garage, use AI to engineer it, and somehow build a virus that will kill everyone don’t know what the hell they are talking about! Of course bioweapons are extremely dangerous. In fact, viruses and bacteria have killed more humans throughout history than almost anything else. HIV alone killed tens of millions of people, yet today, if you have access to effective medicines and take them properly, HIV is generally no longer a death sentence. COVID-19 killed millions. Why doesn’t it kill at anything close to the same scale anymore? Not because the virus disappeared. It is still here. We developed collective defenses against it through our immune systems, prior exposure, vaccines, treatments, and better medical care. And this is exactly the point. The best way to fight biological threats, whether natural or synthetic, is to use AI to develop vaccines, treatments, antibodies, antivirals, and eventually engineer our immune system to create much stronger defenses against them. By the way, it is already possible to make synthetic viruses. You don’t need some hypothetical superintelligent AI model to do that. We have had sophisticated molecular biology and genetic engineering for decades. So how many people have actually died from synthetic viruses compared with natural viruses killing millions every year? And if someday there really is an AI capable of making some unbelievable “supervirus,” then why the hell wouldn’t that same AI make it even easier to develop defenses against it? Or cure diseases, for that matter? Where is this damn superintelligence that has cured a single major disease?! These AI companies and AI doomers keep talking like, “OMG, AI is going to become so unbelievably powerful that it could kill all of humanity!” Then why is nobody asking the obvious question? If your AI is already becoming this godlike, unbelievably powerful intelligence, why hasn’t it cured anything? I mean ANYTHING. Where is the cure for cancer? Where is the cure for Alzheimer’s? Where is the cure for aging? Forget those. Where is the vaccine that prevents the common cold? You are telling me this intelligence will soon be smart enough to engineer some magical virus capable of wiping out 8 billion people, defeating every immune system, every vaccine, every antiviral, every laboratory, every government, and the entire global biomedical community… …but somehow it still can’t cure one disease? I call that greatest intellectual dishonesty ever! At least WE actually know how to cure things and save millions of lives with our supposedly stupid human intelligence compared with this future “superintelligence.” Humans eradicated smallpox, which killed hundreds of millions of people throughout history. We turned HIV from a almost certain death sentence into a manageable disease. We developed vaccines in record time against COVID. If we had the same AI back then, would have saved millions more! We engineer immune cells to kill cancer. We developed antibiotics, antivirals, monoclonal antibodies, gene therapies, organ transplantation, and thousands of medicines. We aren't fast enough but we did all of that with our ordinary human intelligence. So imagine what actual superintelligence could do for medicine! And here is the part that really makes me angry. If you actually have, or are close to having, an AI capable of curing diseases and saving millions of lives, and you are deliberately slowing it down or refusing to make those capabilities available, then we also need to talk about the human cost of THAT decision, which you fearmongering people are going to be responsible for! More than 150,000 people die every single day around the world. Every. Single. Day. More than 90% from Cancer, heart disease, infections, aging. How many die because of AI? ZERO! Talk about the people dying TODAY. Talk about curing cancer. Talk about stopping the next pandemic before it starts. Talk about developing universal vaccines. Talk about engineering our immune system so viruses become almost irrelevant. Talk about curing genetic diseases. Talk about reversing aging. Talk about saving millions and eventually billions of lives. Instead, we constantly hear this “AI WILL KILL US ALL!” crap, delivered with absolute certainty and with this smug smile on your faces in front of cameras, as though imagining a science fiction extinction scenarios. I am actually angry about this. Each one of you causing a delay in AI advance every single day will be personally responsible for those 100 thousands deaths that could have been prevented! Because if you truly believe intelligence is about to become this powerful, then the greatest question humanity should be asking is NOT: “How could this intelligence hurt us?” It should also be: “WHY THE HELL AREN’T WE USING IT TO SAVE EVERYONE WE CAN?” And if superintelligence really is coming, then make sure one of the first things we do with it is make humanity biologically damn near impossible to kill.
Well, I’d add one more with myself, as one with a PhD in biology and another PhD in AI and now working in both, to make n=2. Generating a hypothetical genome blueprint of a virus from LLM versus generating a true virus are completely different things. It is either an intentional attention-harnessing lie or true ignorance. The material, the manufacturing, and actual biological viability of paper-to-physical transformation is the gap you need to close. Like drawing a design of a chip or A-bomb, versus actually make one. You have, and can add more checkpoints and guardrails all over this long chain of paper to physical transformation. Fear mongering is not well founded, and mostly emotional manipulation.

so cute, also maybe a very useful skill to defend against rage baiting

Not only I am tired of these wild AI speculations of impeding doom from self important people: I resent them. I actively resent people proposing to crash the economy or proposing authoritarian control over my life and other people's lives with idiotic and dangerous ideas like chip control or bans or tracking researchers. Every idiot in history who's taken the approach of "the ends justify the means" to solve an imaginary future disaster created the very disaster they wanted to stop. See Population Bomb leading to the one child policy and Communism leading to Mao's mass famines and Fascism leading to the death of tens of millions of people and war. These solutions are evil and worse than any disease that they propose to solve. It you believe you can actually predict the end of the world then you are as insane as the Heaven's Gate cult that killed themselves in the 90s thinking UFOs were coming to transcend them. Not only should we not take your policies and fear mongering seriously, we should actively throw out any and all of your proposed solutions because they come from a place of delusion. I don't give a shit that you work in the industry or think you saw something or that you want to virtue signal on X. You are actively contributing to a horrible future based on baseless speculation that has no grounding in reality. Don't confuse expertise in a domain with ability to predict impact of that domain or frankly to make predictions a decade out better than a dart throwing monkey. They are orthagonal skills. How's Hinton's "we don't need to train Radiologists anymore" working out? How did the Population Bomb work out? The global cooling second ice age? Peak oil? Just because someone is a bridge engineer does not mean they can predict the impact of bridges on society or that they have any actually useful insight at all on the complex, ever changing system called life. There are people dying in wars right now. Children starving. Homelessness. Dictatorships. In short, real problems. And we're supposed to drop everything to stop a made up problem in your head? Pound sand. We don't care. And we are not going to remake society based on you scary monsters under the bed delusion.

The self-knighted high-MTS circle is the worst. They make lots of money, have unlimited compute, unconstrained egos, and access to a frontier toy. They keep telling everyone the toy is so dangerous that you cannot have it, but they will use it to claim all the credit. “If you want to cure cancer, please reach out to one of the MTS members who has access so they can be on the Nobel Prize.”

Only rich people can own a taxi fleet, and when Uber happened, it removed some of that gatekeeping. But cost of buying a car to Uber is still high. CyberCab will democratize this even more, more people can afford to buy them and run their own fleet, be the boss, instead of buying a more expensive gas car and working for Uber, or driving a taxi and working for the owner
Replying to @Jason @farzyness
If Tesla sells the cybercab, then why can’t the uber drivers buy a couple cybercabs and run their own fleet…. 🤔

That's how things are in NY these days, they never gave Lenin credit for winning the mayoral election either

People banning data centers are also slowing down adoption of renewable electricity, and prolonging the economy of scale advantage fossil fuel energy sources currently have over renewables
Behind the New York data center pause is legislation that could impact existing facilities Legislation that’s been put on the back burner while the moratorium is in effect would require large data centers to procure more electricity from renewable sources.utilitydive.com/news/behind-…

California new car dealers Q2 report came out today (cncda.org/wp-content/uploads…). Tesla's sales increased 44% from Q1 to Q2, and 12% from Q2 2025 to Q2 2026. This data directly from the dealers makes Cox/Kelly Blue Book's Q2 estimate for US (only up 6% QoQ and down 13% YoY) looks even more suspect. Tesla's EV market share in CA also increased to 57% in Q2, much higher than Cox/KBB's estimate 50%. Tesla's EV market share increased for 5th straight quarters since Q1 2025, and now at highest since Q3 2023
Cox/Kelly Blue Book's Q2 US EV report is out, they claim Tesla sold 125k cars in US coxautoinc.com/wp-content/up… But they are almost certainly off by >40k too low. Below is my math: Out of Tesla's 480k global sales, we know per CPCA that China had 126k; European registration data showed 90k, if US only sold 125k, that would mean Rest of World (RoW) sold 139k cars, how is that possible? (it's not) Almost all the cars Tesla sell in RoW are exported from China. Again per CPCA, Tesla China exported 128k cars in Q3 (April-June), but shipping has delays, some cars sold in Q2 are probably exported from March, and not all cars exported in June have been sold yet. In the 3 months from March to May, Tesla China exported 121k cars. Split the difference, lets say China exported 125k cars that are sold outside of China. Based on European registration data, of those 125k cars from China, at least 30k are Model 3 sold in Europe in Q2, and there are only ~95k cars available in RoW. 139k sales in RoW is mathematically impossible, off by >40k. Since European and Chinese data were both official registration data, the most suspect number in Tesla's global sales picture is US numbers based on Cox/Kelly Blue Book estimate, and it's not a small error, they are off by >40k

Instead of banning data centers like NY, this is the right way to pursue both AI and clean energy transition, and will lead to both stronger economy and cheaper more abundant electricity
