String Theory and the Multiverse

“ Until we have more information, don’t be fooled by the headlines: these aren’t brilliant estimates or groundbreaking work. It’s guessing, in the absence of any good evidence. That’s no way to do science. In fact, until we have better evidence, it’s not science at all.”

Substitute “ideas” for “estimates” and this would apply equally well to String Theory and its pseudo-scientific Multiverse. Right? Or does our scientific philosophy vary according to what is fashionable?
