It only increases the value of that skillset if it's in demand. Look, I'm on your side on this, I've learned all this stuff and it'd be nice if it was in high demand. But it's just not. Most people's experience of apt-get stops at a Dockerfile, most people never learned vim and never will because they have VSCode, most people do not really know how to use bash and have never recompiled a kernel.
It's a truism that you can do stuff a lot cheaper yourself if you have these skills than paying a cloud to do it for you, but cloud services have grown like crazy for over a decade now and show no sign of slowing down. UNIX is fundamentally a user-hostile operating system, it will never change, and it's nice for those of us who learned it that we can sometimes convert our rapidly-obsoleting skills into savings (sometimes), but it doesn't seem likely to stay that way. The Linux vendors just haven't improved the usability of their platform at anywhere near a fast enough pace to keep up with the cloud vendors.
