I mean, I admin my own servers. But I learned Linux as a kid when time was cheap. If you didn't have that experience then yeah it may make sense to just use as much cloud as possible. Sysadmin is just unpleasant even when you do know how to do it.
Time is finite and there are more things in this world than we can ever afford to care in a single lifetime, not caring is a matter of budgeting that finite time so we can live our lives in a fruitful manner.
Wrong, wrong, wrong. You spend a similar amount of time, but on different knowledge and tasks. And I'm saying I find my skillset more enjoyable and more useful compared to the vendor lock-in and Tower of cloud services of Babylon that is AWS/Azure/Google.
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.
