Have you thought about maybe looking for someone to Co-GM with you? You don't necessarily have to be friends with them or even have personal conversations. Also to be fair I've met plenty of people that I consider RP friends that I don't talk about personal stuff with. Just have someone that you...
I've never actually thought about a futuristic fantasy though I have no doubt it would be fun. I could try giving it ago but I'm trying to get another fantasy RP to take off first. Which oddly enough is a western fantasy like what @Murdergurl described.
Once I've done that I'll DM you and see...
