Linus hasn't programmed much for years. He is a manager. I imagine lots of managers are seduced by vibe coding. Programming can be a real slog and takes so much time. Why walk when you can drive?

The problem isn't with Linus losing his skills but sustainability of the entire FOSS space. I don't think many young programmers are ever going to learn the lessons Linus did as a young person and those lessons are still very relevant for low level code working closely with hardware. When the pre-LLM programmers age out I think we are going to be treading water for years with LLM regurgitating variations on the same old human code without much direction or innovation.

It is arguably a different situation for something like webdev which is mostly paint by numbers or enterprise software that is solving the same problems over and over.
