I frequently do day trips, or at one point monthly rentals, to various cowork offices to get that interaction with “more senior people.” While I couldn’t ask overly specific questions of those around me, we all tend to help each other the best we could. I don’t live in SV (Florida here), but it was kind of interesting. It’s not a complete solution to the problem you’re describing, of course, but it built network and I have some friendships that grew from it. Also YMMV on how social people are around you, we kind of had an unofficial card system, red meant don’t interrupt and green meant I was open for chatting.
