Growing up rural, I had about zero people interested in technology around me, even less about programming. But, there was a few of those "curious people" who I talked to about computers and programming. They mostly had no idea, but they were interested, and engaging to talk about, they acted more like a wall to bounce the ball against, rather than actually mentoring me for programming, or whatever.
Anyways, these people, the curious ones, exists everywhere, even in rural areas, even in places with less than 1000 people. They tend to be seen maybe as eccentric, odd or weird, but you can talk to them about everything and anything, and you'll still probably learn something, if not about the subject, maybe about yourself or maybe about your new friend :)
There's not many geniuses without an ecosystem around them that produced them. And even if there are, how would we know about them if they weren't well connected enough to start mattering?
