I agree with this. I cannot find talented and senior folks who fill the niche of my team (deep understanding of Linux systems, containers, and operating distributed systems). There seem to be a lot of SWEs in the world and very few SREs, let alone vanilla systems administrators for hire who are really good.
I think as an industry everyone is pushed towards software engineering and the large clouds have vacuumed up everyone worth their weight for operations. We make it happen but it’s so stressful because our team and workload balance is so far out of whack.
