This is such a crazy take for me. Any profession that matures eventually specializes. I wouldn’t expect the same person to pour my foundation, install the plumbing, and wire the building. Yet in an ever expanding field we expect someone to be able to do it all. Also saying people who don’t code have no stake so egocentric.
Pouring foundation, installing plumbing and wiring the building is specialized by the physical necessity of these activities, which cannot be repeated without mistake at a great cost. That justifies specialization. Unlike building a bridge, compiling software is essentially free. QA, release engineering and database design can and should be repeated and iterated on by software engineers, because it is a necessary part of the development and removing it from the expected work distorts incentives.
