If Ai can be trusted to do all the trivial tasks and if non trivial tasks require a scaffold of trivial practice, where are we going to keep finding the people qualified enough to actually do the non trivial stuff?
If we hit the point where a senior engineer reviewing the output from an AI can effectively replace a team with a senior engineer and 5 junior engineers, you’re right that it isn’t wise to simply replace all those junior engineers with the AI. Unless you’re confident that the AI will be able to replace that senior engineer soon, you _need_ junior engineers who can build up the experience needed to step into that role once the senior engineer moves on.
But you _can_ get rid of 3 or 4 of those junior engineers. The remaining junior engineer(s) will still need mentorship from the senior engineer and will still do “trivial” work that needs oversight, but they will be able to pump that out at a high enough rate to replace a few of their pre-AI peers.
Basically, I’d imagine the org chart at most companies will look pretty similar to now, except you’ll just have fewer people at each level.
