Have they evaporated or just morphed into SJW’s
They pretty much morphed into modern consoomer culture. They still have almost all of the same aesthetics and irritating opinions; the glasses, the gut, the ugly beards that just don't look good on them no matter how well they're groomed, the same dull apathetic pseudoliberal outlook, etc. Its just that music and fashion snobbery have been replaced with corporate snobbery.
They got old but didn't grow up at all.
I think some of them did but I don't think there's neccesarily a high correlation between having been a hipster and trooning out, much as we might want to think there is.Either that or they all began to troon out because nothing says "I'm special and unique" like chopping your own balls off.
The funny thing is that back in the mid-late 00's hipsters (although they weren't called that back then) were far from being SJWs because what was considered cool was basically doing "provocative" and "shocking" things mostly just for the sake of being edgy. The whole culture of "cool" urban young hipsters revolved around that
