A rebuttal
This guy, Peter Woit, author of the book and blog of the same title,
Not Even Wrong, thinks that strings do not exist due to a severe lack
of actual evidence for them:

Seeing as it has been postulated that it would take a particle accelerator
the diameter of the Milky Way galaxy to detect a string, we either have
to find other ways to prove their existence or start pursuing other ideas.
Though maybe if we can get access to these guys:
