No, I think the reason human expertise on the internet is dying out is because we have a cacophany of voices trying to be heard on the internet, and experts aren't interested in screaming into the void unless they directly need to do it to pay their bills.

I would say that going onto Stack Overflow to answer questions made me a better coder - yeah, even with the cacophony of bullshit and repeats. It's almost more offensive for that job to be taken by "AI" than the job of writing the stupid code I was trying to help people fix.

[edit] because I kind of get what you're saying... I truly don't care what marginal benefits people are trying to get out of popularity in the high school locker room that is the Social Media internet. I still have a weird habit of giving everyone a full answer to their questions, and trying to teach people what I know when I can. Not for kudos or points, but because the best way to learn is by teaching.
