If one truly believed in LLMs being able to replace knowledge workers, then it would also hold that they could replace managers and execs. In fact, they should be able to do it even better: LLMs could convert every company into a "flat" one, bypassing the manangement hierarchy and directly consuming meeting notes from every meeting to get the real status as the source of truth, and provide suggestions as needed. If combined with web-search capability, they would also be more plugged into the market, customer sentiment, and competitors than most execs could ever be.

You have to move up or down to survive. In 10 years we'll either be managers (either of humans or agents), or we'll be electrical engineers. Programming is done! I for one am glad.
