I think a primitive bot based upon current LLMs could easily replace a project manager for, perhaps, 95% of what they do. Middle-management easily 99.9%.
As we can see with how things are panning out, it's another question altogether about replacing engineers. Even Jensen himself is confused and completely wrong on that one.
Couldn't agree more about the enshittification of the world based on current LLMs either, I'm of the opinion that genuinely creative and worthwhile content will rise to the top - leaving the dross firmly on the pond floor.
