<p>Please, some of us are long NVIDIA...let us cope in peace. :-)<p>Here is the thing nobody wants to say out loud or they are too dumb to realize. AI is intelligence, and intelligence has almost never been the binding constraint on productivity.<p>So you will get no productivity increase from the AI bubble. Yes, you read that correctly.<p>The test is simple, if raw brainpower were the bottleneck, you could 10x any company by hiring 200 PhDs. In practice you get 200 brilliant people writing unread memos, refactoring things that worked, and forming a committee to rename the committee. Smart has always been cheaper and more abundant than the discourse pretends.<p>Every real productivity revolution came from somewhere else like energy (steam, electricity), capital stock (machines that do the physical work), or coordination (railroads, shipping containers, the assembly line, the internet).<p>None of these raised the average IQ of the workforce, they changed what a given worker could move, reach, or coordinate with. Solow old line basically still holds. The output per worker grows when you give the worker better tools and infrastructure, not better neurons.<p>Meanwhile the actual bottlenecks in a modern firm are regulatory approval, legacy systems, procurement cycles, customer adoption, internal politics, and physical supply chains that don't care how clever your email was. A smart brains intern at every desk produces more artifacts, not more throughput, and in a lot of organizations, more artifacts is actively negative ROI.<p>Jevons does not save you either, cheaper cognition mostly means more slide decks, not more GDP.<p>So the setup is that models are commoditizing on one side, and on the other side a product whose core value add (more intelligence, faster) is aimed at a constraint that was never really binding. This of course a rough combo for a trillion dollar capex supercycle.<p>Fun for the trade, while it lasts, but there is no thesis. Just dont tell CNBC and short NVDA on time ,-)</p>

<p>"Almost everything you said is false" and yet you could not name one thing. If my claims were wrong, you would correct them. You did not, because you can't.<p>You claim the Artemis II review convinced skeptical experts.What actually happened was Isaacman ( or shoud I say Jared? ) convened a January meeting to present NASA rationale for flying a heat shield they already knew was flawed.<p>CNN was denied access, only two journalists were invited, largely off the record. Isaacman own words afterward, that the meeting "only reaffirmed my confidence", tell you the conclusion preceded the review and show a level of manipulative representation, that hint he will go far in the current administration.<p>The most qualified skeptic in the room, Charlie Camarda, a former NASA astronaut, heat shield research engineer, and member of the first shuttle crew to fly after Columbia, walked out unconvinced. He said NASA "definitely does not have the data to show that it's safe" and that the agency was using "the same flawed thinking and crude analysis tools, similar to Columbia, similar to Challenger." He wrote an open letter to Isaacman warning that this "exhibits the same patterns that preceded past catastrophes." He estimated 1-in-20 odds of disaster.  Danny Olivas was a man on the payroll, Charlie Camarda no.<p>On Polaris Dawn you say Isaacman, did the same tests and reported results just like the spacesuit engineer. You are making my point for me. The spacesuit engineer was Sarah Gillis, a Lead Space Operations Engineer at SpaceX who spent 11 years training astronauts, including the NASA crews for Demo-2 and Crew-1. She was there because she helped build and develop what was being tested. Isaacman was there because he paid for the mission.<p>Following test procedures that SpaceX engineers wrote, on hardware SpaceX engineers designed, inside a spacecraft SpaceX engineers built, does not make you an engineer. It makes you a test subject with a checkbook. A patient in a clinical drug trial also "does the same tests and reports results" as the researchers but that does not qualify them to run the FDA.<p>Which brings us to the question you seem to have avoided.<p>Why was Isaacman selected as NASA Administrator? He is the CEO of Shift4 Payments, which has a five year global payment processing deal with SpaceX's Starlink.<p>He has no aerospace engineering background, no government management experience, no science credentials. During his confirmation hearing, when Senator Markey asked about his ties to Musk, Isaacman claimed they were not close :-)) and that he had not discussed his NASA plans with Musk...<p>But when Markey asked whether Musk was present at his interview with Trump, a simple yes or no question... Isaacman refused to answer.<p>A payments CEO with financial ties to SpaceX, nominated by a president who received hundreds of millions from Musk, who can't say whether Musk was in the room when he got the job... If you don't see the problem, you either are not looking or dont want to look.</p>
