I think it'd just be easier to use virtual reality directly linked up the brain, so things you use in the "virtual reality" are felt by you, you can feel their touch, their sent, their taste and others. So you can create a furry community that is seemingly real in every way. Would require a lot of computational power, but you wouldn't need a planet sized computer if quantum computers are perfected.
Don't you think it is amazing that 250 atoms could compute more than a classical computer the size of the entire observable universe?
