Well, yeah. Then who will become the senior engineers in 10-15 years?
These people are working on destroying the planet to make more money, they absolutely do not care. Our society isn't set up to punish them, but encourage such behavior to even more extremes (see datacenter build outs causing water shortages, electricity hikes, and cancer in poor communities; nearly every politician capitulating on such actions because they don't know better).
Obviously after 10-15 years of experience working as a developer AI will be a senior dev. Probably will get promoted to management with all that experience.
10-15 years? Sadly, most people are declared senior after like 2 years of work.
Anything besides next quarter does not exist.
You can’t pretend you know where technology will take us.
AI will be the senior engineer
Stolen from your competitors, obviously.
You think the people deciding whether to hire more juniors are planning more than one or two quarters ahead? 10-15 years is someone else's problem.
