No, it likely won't be as popular. Might be pretty quiet in general, unless (until..) Reddit shits the bed again or something else happens to boost adoption.
I think maybe the design isn't working ideally, it's relatively complicated stuff and "federation politics" makes it infinitely worse. I think it's going to be a hard sell for casual users.
Of course, I don't think the place is dying off completely any time soon, either. (And the "bunch of nerds" era which we're at, relatively speaking, was arguably the least sucky Reddit period anyway - you can't have Reddit's user count without a large helping of extra toxicity coming with it)
