Why would you expect that just because someone can do your job, they should join you as your peer? That might be true for more junior folks - they have proven they are on at least the same level, emphasis on at least. What's wrong with more senior folks, who may also have skillets you don't, still retaining their tech chops?

I have no problem with my manager being more technical than me or being better at what I do, as long as they don't try to do my job instead of theirs.

If they are actively trying to do my job then by all means stop being my manager and become my peer instead.
