My apologies. My intention wasn't a dig at engineers themselves, but rather the trend of employers seeking "full stack" engineers, and the implications of them shopping for a singular engineer willing to do the job of multiple engineers-- IE be taken advantage of, and the first to be let go, because of a lack of specialized domain knowledge, etc.

The truth is that there is value in both a generalist and a specialist.

It just means he can't do it by himself.

Yours won't be perfect, but you can do the whole thing by yourself.
