I always wondered what "clever" people expected from crypto, apart from getting rich quick schemes. Boring.
We had such know-it-alls still with their pimples from Frauenhofer and Max Planck giving presentations. Even back then, 99% percent of the audience were skeptical, but sadly too many decision makers are just emperors with no clothing. There were so many immature, useless loud speakers given a junior professorship because old morons have FOMO too. That must have sucked for the valid academics with proven achievements. I'm glad I'm not one of the ones waiting in queue. There no single project having any sign of impact, naturally. While that can be said of a lot of academic work, crypto: more buzzwords, even less delivered.
As an outsider I have been most interested in the ability for blockchains such as Ethereum to serve as an automated escrow
