Since you mentioned AI, I'll also give my perspective on that:

I'm concerned that it will, literally, suck the blood of good engineers to pump into bad ones.

Some 10 years ago, I would tell juniors that donating blood is a good thing to do and something they should aim for. I am not so sure about that anymore. Today I would teach them to sharpen wooden stakes.

I want promising junior developers to survive. That's an important prerequisite for being able to be a good developer. I don't want them to be too naive and die off.
