Well, stack exchange already turned me into a bad programmer, so... I actually think that there are so many layers of software between the app you develop and the machine, that it is almost impossible to know every detail. There are language, runtime, compiler experts that will certainly know more in their respective domain. I develop embedded systems, mostly bare metal and Linux based systems. Being able to read the output of a C compiler can indeed help. But that isn't really my expectation when I develop higher level applications. In general I would support this statement though. Use copilot if it really suggests what you wanted to write anyway and have done so countless times. If it suggest some arcane wundercode, maybe try to write it yourself first.
