What's the next fad

What's the next fad that's going to hit the tech sector?

I got into mobile bullshit because want to get in early so I can retire to Thailand and have my own harem of 5yo boys. But work is slowing down drastically. Where should I go next?

If you master that, you might get your harem of children and not even have to go to a shithole country ruled by a sensitive monarch.
Given that half the world can't tell the difference between cartoons and real CP, I doubt that would work.
