This comes across strongly any time you hear management talking about "fungibility of engineers". Everyone is a full stack everything engineer, and AI makes that even easier for them to trick themselves into believing.

If anything, I feel like AI has made domain expertise more important, not less, as the "confidently wrong" error case for agents has no one able to sanity check it. At least before AI a human would dip their toe in the water and usually realize that having no idea what they were doing, and not even being able to understand what the comments mean, was a sign that they need to go find someone more experienced to help.
