I live in Silicon Valley, and there's a billboard along highway 101 near San Francisco that's an ad for "BlockChat", a "Web3 messenger" that uses the blockchain instead of a server. I went to Google Play to look at the app and it's only had 10k downloads total. I really don't understand how blockchain would help with messaging, and there's a bunch of limitations (eg you can never delete messages). People just trying to shoehorn AI and blockchain into everything.
