The powered wig is the must-have ubiquitous tech device that everyone has in 2057. It’s our version of your era’s smartphone. It is an AI-powered neural interface used to communicate with people, get the latest news, watch some vids, or even check your emails, if you still do that.

It’s essentially the “killer app” for AI, taking a good 21 years for the tech industry to figure it out. Don’t ask about the form factor, that’s a long story. But I promise it looks less silly when everyone’s wearing one.

Oh, and a little tip from the future: don’t overpower your wig.

It rises and falls. It's right in the title! Perhaps it has little jets, or maybe a particularly specialized form of antigravity.
