I still think you've missed the point. You can be grateful for the many gifts you've received and still wish to have had engineering guidance from a trusted mentor. There is not enough time in a life to go down every single rabbit hole; it's nice to have experienced people accurately point out where the rabbit holes are. Non-engineers are not equipped to help spot engineering rabbit holes; they might even tell you that engineering itself is ultimately a pointless rabbit hole.

But even then...that's just my own experience and my own wishes for my past self. I try to give what I wish I had had, of course.. think that's what drives most mentorship, and maybe that's the point you're trying to make, that mentorship is given out of that wistful feeling of wishing you had received advice/help and passing along the lessons that took you too long to find.

But still, if your role is getting stuck alone in the server room or whatever with a team of people who don't understand or respect what you do, good luck.

The point I was trying to make (and maybe failed because I got too focused on my own experience) is that really, not everyone gets mentors, even of the broader sort that you're referring to (which I might say are more accurately called friends or peers). But even if we widen the scope of what mentorship is, it's also perfectly reasonable for field-specific mentorship to be a cultural expectation for software engineering. I think it's a good thing to expect this of each other, and to encourage explicitly making space for the practice.

But again, however you want to widen the scope of what mentorship is, not everyone is getting it. The reason people look under rocks is because they don't know where to look. Or they do know where to look but also know they have blind spots and don't know how to get them addressed. "Look up" is nice and all, but it's a bit rude and distracting when you're trying to build something and need help understanding the foundation below your feet. Sometimes you don't need someone telling you to look up, you need help seeing where to look closer.
