Isn't depending on Claude to administer your systems rather divergent from the theme of "Self-Host and Tech Independence?"
Obviously you should have enough technical knowledge to do a rough sanity check on the reply, as there's still a chance you get stupid shit out of it, but mostly it's really efficient for getting started with some tooling or programming language you're not familiar with. You can perfectly do without, it just takes longer. Plus You're not dependent on it to keep your stuff running once it's set up.
I'm using it to learn unfamiliar languages and frameworks.
But if I didn't know how to do it myself, it'd be useless- the subtle bugs Claude occasionally includes would be showstopper issues instead of a quick fix.
