CRUD is a "hard problem". There are currently no RAD frameworks for simple CRUD apps — nothing like FoxPro or FileMaker of their heyday. The amounts of redundant labor being put in CRUD apps all over the world is insane — and no one seems to be doing anything about it.
So yes, I am mildly passionate about CRUD apps development, and it is not hard to imagine someone who is really passionate about it, coding next-gen rapid development environment for CRUD webapps weekend after weekend, and on its way to becoming yet another garden variety tech billionaire.
If some industry is "boring" and monotonous, it is ripe for disruption by something exciting. Truck driving. Filing taxes. Accounting. Paralegal. And yes, CRUD app development — will be automated nearly out of existence soon.
