Or maybe it is that SpaceX is doing simulations on a level ahead of what everyone else does. Here's one of several amazing videos from SpaceX simulations.

This is the same thing they are doing on the Tesla side of things. So apparently every car they manufacture has a "digital twin" that is created when the car is manufactured and serves as a data hub for all the data the real car sends back to the mothership over the life of the vehicle. This allows them to simulate potential issues and design problems that are then input into the manufacturing chain to improve subsequent cars. I bet some other automakers are probably doing something like this but I don't recall anyone talking about it at any conference yet.

  This has been done on jet engine fleet monitoring for well over 35 years. It has nothing to do with AI, or am I missing something?

    Not missing much, just that production integration of AI has become a feature-addition to a good data model. The digital twin model is just a data model. Advanced simulation could be considered AI, but that border gets fuzzy with "just the same math everyone has always done, with more compute."

  They're so digital they can't get the car doors to align with the body in the real world :) Source: the one Tesla that i've test driven had a crooked left rear door. Straight from the factory.

    Yeah this is a common and baffling problem with the cars that occurs to this day. Its become a meme at this point. There are loads of people that can help them out with this issue as it is a long solved problem(hence tons of consultants). It seems like the consensus is that cars coming out of Fremont will forever be a mess until the factory is torn down and completely rebuilt with modern design. In some prior Tesla talks employees discuss how the line is just poorly laid out in Fremont and that leads to bad lead times which result in rushing at certain stations. It was an abandoned Toyota/GM factory and is filled with hacks and bandages. I hear the Shangai cars are much better. Heres to hoping that they have considered this problem when designing the Texas and Berlin factories.

I mean the author seems to believe that the SLS is a space program, when clearly it’s a jobs program. Nobody in congress or the senate gives a crap about if the SLS achieves anything, as long it keeps paying for jobs in their home state. Even senior leaders at NASA hate the SLS, and the fact that it hamstrings into using ancient technology that was difficult to use, even before everyone with the knowledge to operate it retired. NASA would much rather be developing new rocket technology, rather than painstakingly rearranging old rocket technology. But doing that would risk Apollo era jobs, so instead we have the SLS.

I dont get what this has to do with AI. This is a discussion of CFD optimization, by using non standard indexing to link cells turbulence information.
