Its kind of insulting how many people look at other industries and think they can "solve" the problems with their simple solution. As if the people in these industries havent been thinking about this problem for decades.

Industries can be trapped in a local optimum. It sometimes a fresh take (and a heavy bag of investor money) is needed to get to a higher level.

Reminds me again of crypto. Lot of stuff being done in banking and payments happens for a reason. Or because someone from outside like politicians meddled into it. And forget that people are extremely gross when it comes to getting their bank balance wrong...
