The DeFi thing has finally pushed me to look at crypto again, which turned me on to metamask (via Brave), and after experiencing the UX, it's glaringly obvious that this is the next big thing. Nobody even talks about it, but the fact that I can "sign in" to my "brokerage account" simply by visiting dydx or unisawp and authenticating securely with my browser is pretty incredible.
People are claiming to be excited about DeFi because everyone loves unregulated derivatives and lending at insane APYs, but I think the real reason this has taken off is because the UX makes the future feel so real and achievable.
I'm just scratching at the surface now, but it's clear we've come a long way since bitcoin. I won't be shocked if it turns out bitcoin becomes seen as worthless old technology, but blockchains will never go away.
