Yes. The ones who maintain high risk system software that allows all these machines to be able to train LLMs, compile the systems software or maintaining systems that ingest 2% of the worlds traffic are the ones who are making a lot of money out of this.
Not the ones maintaining frontend web apps or "vibe coding".
All the people I know in the US with those skills make huge amounts of money- at least, the ones who haven't already retired rich.
