I'm referring primarily to gaming subcultures (board and video). Tech illiterate may not be the proper term. But most geeky people I know (even the ones who build their own PCs, and dabble in scripting) have a very cargo-cultish understanding of computing technologies.

Dilettantes, perhaps?

Even a cargo-cultish understanding is an understanding and not tech illiterate. I wouldn't call someone who can build a pc tech illiterate.
