Blockchain was invented to
be a financial application. I see no reason to believe it could/should be anything more. And a singular application technology is perfectly fine.
Everyone is upset with cryptocurrencies being an overvalued asset. But, that is a purely social phenomenon that happens entirely orthogonally to the technology itself. I mean, the same phenomenon has happened in the past to shoes and children's stuffed animals.
It can happen to literally anything that you can convince get-rich-quick gamblers is worth a gamble on.
