Perhaps billionaire, unless the current startup bubble bursts first.

Let's see:

   LinkedIn -- get an idea of income via job category
   Tinder -- hmmm, someone "looking for love"
   Uber "walk of shame" -- someone not just looking

I'll stop now. The possibilities are way too creepy for me. But there will be plenty of narcissistic hipsters who see nothing wrong with any of that.
