Something I've noticed as I've started to more actively try things with crypto wallets(which have made inroads on being identity/login solutions) is that there is a refreshing transparency and friction to the on-chain interactions. There are many things that cost a fee and make the wallet prompt for my password again when interacting with blockchains, but I haven't used Ethereum, so I've never seen a fee above a microscopic amount. And even given that the fees don't impact me, it throws the reality of what it costs to run the system in my face, making the low friction and opacity in big tech UX look shady by comparison, like, "well, why are you rushing me through this?"
Something significant happened to our trust model when we made that little leap from computer systems still "driven" by front office desk clerks and receptionists to fully automated ones - the ability for the intermediary to properly look out for you disappeared under the lens of KPI, as OP notes. So computing tech became more of a weapon for all sides - a thing to exploit or be exploited through at hyper speed. While the crypto way of doing it has a long way to improve still and also suffers frequent headliner exploitations, the core of it reminds me of the past in a good way; both "no questions asked" and "gets your permission". It just needs "smart enough to spot and correct grave errors".
