Most things built 'out in the world' have hardly any business logic, they're all just CRUDs.

In enterprise this is obviously the opposite way around. It's actually super frustrating to watch discussions that ignore this, it's a really big problem on tech twitter etc especially, where people advocate for certain stacks or ways or working or whatever that make it clear as day they've never had to build a business system, they've just been building CRUDs, so they're incapable of understanding why experienced devs who have disagree with them.
