"What Is (And Isn't) Scientific About The Multiverse"

Not that we'll know anytime soon, but I don't like the idea of the multiverse. I do like the author's assertion:

So why do so many theoretical physicists write papers about the multiverse? About parallel Universes and their connection to our own through this multiverse? Why do they claim that the multiverse is connected to the string landscape, the cosmological constant, and even to the fact that our Universe is finely-tuned for life?

Because even though it's obviously a bad idea, they don't have any better ones.
