You'd see a lot more from both sides if the motivations were there. The motivation in safety critical stuff is not killing people. It won't matter if I get a boring CRUD app feature to near perfection, I make the same regardless, and that's true in private companies and government.
I think the safety critical developers maybe have some deep itch to scratch and compensation is way less important to them (otherwise they should be making millions in salary given the stakes), but we don't need to use that bar for every developer or product.
But maybe AI will commoditize all of the old boring CRUD apps and those kinds developers are only worth $20-30/hr.
