Invisibility would be great. Of course I'm a mischievous type of person. So I would be up to no good.

How about "none of the above"?

You've missed one. Even though it's never happed to me (as yet) I'd like to have a special personal computer that can track down and zero in on those mongrel extortanists that send out encryption codes that block your files until you pay a ransom. After my special computer tracks them down it'd zero in and blow up their computers in their faces , hopfully doing considerable damage to their personal features. Is that too nasty of me ?

I'll take the space arc. But if the AI companion looked like Kate Upton and had the sex drive of a porn star, that would be a difficult one to turn down.

That was a no brainier for me. Interstellar travel

Make me invisible. Maybe no one will shoot me.
