You have a passion for CRUD apps. You dream about CRUD in your sleep.
You attend (or give talks at!) CRUD conferences. Your bookshelf has at least five books on CRUD. You attend CRUDathons, and maybe have won first place in the most READs or most CREATEs category.
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.
