I'd say .app is probably a shoe-in. The other short ones have a pretty solid chance of seeing real use.

The long ones, not so much. How popular are existing TLDs like .info or .name?

Given sufficient time, maybe the others will amount to more than an unabashed cash grab. But not this decade. Probably not the next, either. And at that point, you're talking about a situation where "remembering a domain name" is even more of a broken process than it is today.

How will we connect to computers on the global network of fifty years from now? Two hundred? I'm betting it's not going to look like http://blog.johnjohnson.photography or whatever new list ICANN releases next time they want to play.
