To me the sysadmin role always felt analogous to an Apache scout or something, where one's deep knowledge of the computational terrain they inhabit is of primary importance; in other words it was the ultimate version of "the best solution is the one which requires the fewest lines of code" -- no need to roll by hand what `awk` or `systemd` or BSD jails or what have you can already do, much better, and in a much more thoroughly tested way than what you as an IC could do. Indeed to this day when I work with people who started on the sysadmin side and only later made the jump to SWE I find it easier to communicate with them because I know there's this shared scout sense we both possess.
What's the deal? I have my own theories as to the decline, but I'm curious to know your thoughts.
But there's still plenty of backend, devops, SRE, cloud whatevers, etc. if that's what you want to do. Probably you'll be working for a infra provider rather than a business itself, like the old days, though.
The more to the right, the less I had to interact with bare metal servers, but apply my knowledge of building them and operating almost every day.
For a while after that, I made gears, mostly bevel gears, until Long Covid took me out of the work force, and put me in the precariat.
I don't see systems administration as sufficiently time consuming to be a full time job anymore.
But this is basically the role I had when I had the title, so my perspective may be biased.
Sure the work has evolved too but a lot of the fundamentals are still the same and you still massively benefit from having that background context and history.
There are a lot of fresh "bootcamp cloud engineers" who know the buzzwords and know which buttons to click on AWS but they don't have the depth of knowledge to safely navigate on their own.
They can give you a 30 minute spiel about why you must move to serverless ASAP but ask them what 777 permission is and they have no idea.
Not that being a beginner is any issue at all if you are self-aware but some of them are lost in YAML and buzzwords and have no idea about their gaps in knowledge and experience.
