Everybody is interesting if you get talking to them. You just think the guy who collects your trash is uninteresting and never talk to him (or do you?). Sure not everyone has the same background, and so they are interesting in different ways, but they are all interesting.
This is exactly what I meant, but even beyond relatively common jobs, if you're likely enough to bump into open people, there's a good chance some of them will be doing more niche interesting things too
Interests must align. People must know common jargon which convey high density information faster. I would like to have positive ROI on the conversations that I have.

That's part of the dice roll. Sometimes interests do align, sometimes they don't, but someone looking for ROI is easily spotted and ran away from. Chemistry and common ground are a matter of luck.
