I get 'useful' stuff from AI all the time. Nothing major, but little timesavers, unique character art for a DnD game, language and grammar suggestions when I'm writing short stories with my wife. That kinda thing.
Crypto offers me nothing. I have absolutely no use case for an average person's life. I'm sure there are businesses that can utilize crypto to some benefit, but frankly I couldn't care less about their ability to hide money and evade taxes.
