I don't know if procgen tech can ever be good
Look at Kenshi. The whole world is hand made, but there's no story, no quests, and no voice acting. It was made by a very small team, and its insanely fun and addictive because the systems are complex, engaging, and rewarding. (The old buzzword for this was 'emergent' gameplay).
There's no reason why a bargain bin looking indie title made by one guy should be more fun to play than a $100 million AAA epic. Imagine Kenshi with Starfield's budget; instant greatest game ever made.
Consider Rimworld. In a few seconds the game generates a dozen factions, religions, large continents, multiple biomes, and dozens of settlements. It also has no story or voice acting, yet the gameplay is endless. Fight, trade conquer, survive, exterminate. Another one man project. Sure, the graphics look like shit, but that's where the AAA development muscle should be going. Not quests or voice acting or "muh story."
There is no problem with the tech, it already exists. It just needs smart people to take the right chances. Diablo was nothing more than Rogue with the rough edges sanded off and a coat of AAA paint, and look where that went.
