Roles are necessary because we simply don't have time to be experts in everything.
AI changes the way we contribute.
You're right, we all don't have time to be experts in everything. But that doesn't mean experts aren't valuable, or that experts shouldn't exist.
Anyone that thinks an LLM won't be up to spewing endless Harlequin Romance level prose is in a state of denial. And the cost of tokens continues to drop. This either means the current generation of content gets cheaper or better content becomes affordable through chain of thought token burning. I don't see a problem with that. The problem IMO is pushing a narrative that AI exists primarily to displace humans and the pushback is finally loud enough that it's getting blasted back into the faces of the billionaires. I see that as a good thing. May their endless hedonistic orgy at everyone else's expensive finally become a living nightmare of inadequacy on the hamster wheel of despair
The only way to act is to not produce or consume (to the best of your ability) any slop, and be loud about it. We are being absolutely overrun with low-quality art, prose, and software, and making the production of such unprofitable (and even unfashionable) is the only reasonable action you can take.
