  • He still is involved with engineering things, people just want to think he’s not so they can think less of him.

    E.g with Starship it was his decision (that he had to convince everyone on) to use stainless steel for Starship. If I recall correctly, his current focus is on the raptor engine.

    So far SS seems to have been working well for them, with the ship surviving some brutal re-entries even with missing heat shield tiles.

    This is the progress they’re making on Raptor. And for anyone that doesn’t know, Raptor are the first Full-Flow Staged Combustion Cycle (FFSCC) engines ever flown. A lot of the reductions you’re seeing between the engines is from moving to 3D printing all those channels within the tubes.


  • when they have absolutely nothing to do with AI other than their poorly chosen marketing name

    I worked somewhere once where they had an algorithm that placed items according to rules it was given, and it would output variations based on the rules to give the user some output options to work with. Think A or B could go here, and the different outcomes based on if you started with A or B.

    It was pretty complex, but ultimately it was just a deterministic outcome of many possible deterministic outcomes based off the rules and what you started with.

    They marketed that shit as AI.

    It infuriated me.

    No machine learning, no neural nets, no reinforcement learning, or learning of any kind, just placing things based off rules.

    And don’t get me wrong, it was good, just not AI.


  • Hopefully there are people still working on non-llm type general AI, because i don’t think we’re ever going to get there with LLMs. The architecture just seems wrong to ever get there, and even Altman has said they probably can’t solve hallucinations. We can probably go very far down this road and get them pretty good, but it’s the wrong road if you want a real AI.
