The person whose only degree is Art school dropout, but who's logged many hours coding personal projects, running their own Linux or BSD machines, playing with networking, tweaking a game binary, etc., will wipe the floor with more-credentialed others, at a lot of real-world computer technical stuff.
Compared to person with a Engineering degree, or even a Computer Science degree-- but who spent no time outside of classwork, Leetcode memorizing, and a GitHub profile that was motivated only by FAANG-application coaching.
Those people who couldn't create their keypairs probably have fine raw material for becoming the kind of Technical person you need. But they're just having a pile of information shoveled at them in lectures and homework. And maybe they just wanted a job. And nobody told them that, if you want to be good, you have to put in the hours of quality unstructured learning time.
