What makes you think they won't?

I don't think they will ever have the gravitas of a dot-com, but the unavailability of good .com domain names has led people to accept other TLDs. The popularity of .io in tech is a good example; people prefer $(name).io to iwanttoget$(name)app.com.

I bet we'll see at least one of the new TLDs become as popular as .io. Maybe .app?
