Wow, really going for those white collar jobs. This is going to be an interesting few years.
What will happen is what has happened for the past few years: mostly nothing. People employed, things keep trucking forward.
LLMs do not change the equation all that much: human's ability to imagine is the most scarce resource on the planet and LLMs will not help all that much with it.
Just a natural rebalancing of the Rise of the Laptop Class. I think we'll get more productive as the white collar jobs become more efficient, and less days with 8hrs of meetings and responding to emails from people too lazy to look information up themselves.
