We will never have flying cars for personal use. Of all the things we might have in the future: cyborgs, space exploration, a penchant for ridiculous fashion, we will never have flying cars. It isn't impossible to invent. It is impossible to make it safe.
We can't really have thinking robots either. Let's face it, people, it just takes one loose wire, overly logical computing assessment, or Will Smith before they go haywire. I mean, this robot chick looks nice. She's giving us some kind of weird look, but it's friendly enough.
I painted her in oils on illustration board. She's 16x19. But like I said, just one solar flare later she's opening air locks and flooding the enrichment center with a deadly neurotoxin.
