Self-hosting is something in my experience that helped that I don't see in your post.
(Dangerously) running open source software on the public Interet gave me a crash course in DNS and networking. It also made me very motivated to read up on Cybersecurity risks to my servers.
I find it very effective to read about a common misconfiguration and then go read through the relevant configuration files on my server and try to verify that I have it mitigated.
As unmagical said, we're all slop code verifiers, now, at least some of the time. This isn't actually new due to AI, but the automated junior coder makers certainly make it worse.
QA staff who know automation are incredibly valuable, and often under-appreciated.
There's going to be un-meetable demand for software verification skills, as soon as anytime manages to measure (and start trying to recover) how much money the AI slop code wave is flushing down the drain.
