It's repeatedly stated that while it's still improving, AI is coming for the entry level positions and the juniors first. How many times have you seen AI described as "like an eager junior"?
Why would that surprise you? They aren't stupid. They can see that people are trying to position AI as a way to replace them.
My guess is a lot of those grumpy old guys, on this site at least, are sitting pretty with large bank accounts. So they don't need to worry about their jobs anymore. They could retire safely tomorrow if they wanted. So they don't care.
Just another instance of the older generation trying to loot the future from the younger.
