YT isn't going to drop premium any time soon. Subscriptions are astronomically more revenue generating then ads, and given YT was always operating at a loss until they stopped reporting revenue altogether premium will probably be the only route to scrape by.

Not to say they can't enshittify it by raising prices and adding restrictions, but I can't see them doing anything but trying to force more people to it.

I paid for it for a bit a while back, and it was decent. Of course free tools give considerably better features (adblock, sponsor block, DRM free downloads, better privacy). That and personally not wanting to financially support YT for a variety of reasons has kept me away from it for a long time.
