This is an incredible amount of code for what it offers. I don't think this was intentionally designed at all.
You will be surprised how much code goes into creating harnesses.

Another tactical move is to just stop. You're allowed to exit the AI business. Nobody's forcing you to keep throwing money into the furnace. Just be a rocket company. All of the xAI founders left. Your product's brand name is mud. Just stop doing that and build spaceships.
You misunderstand Musk's motivation. This was never about money for him, but about control over a key technology. One of the main reasons he exited OpenAI was the fact that the other co-founders wanted to create a structure where no one, Musk included, would be able to seize full control of the company. That was the thing that prompted him to leave, which tells you a lot about what he really wanted in the first place…
I just don't get it, I'm sorry.

#304There's some surprising stuff in this codebase. For example, https://github.com/xai-org/grok-build/blob/b189869b7755d2b48... is a "self-contained terminal renderer for Mermaid diagrams", which renders a subset of Mermaid chart types using Unicode box-drawing.

The rocket business is hardly profitable. The whole valuation is based around grok and space datacenters. He needs to keep pumping the hype or else we are in for the worlds biggest crash.

#307They claim to have deleted or will be deleting all the data they exfiltrated. There are independent agencies that will certify destruction of data. For example FTI Tech, Kroll, Epiq, HaystackID and others. No such certificates have been presented. Nothing less is trustworthy.
So I don't think it can ever work without exhilarating the data - rather I am still surprised people don't understand the implications.
