"So it is refreshing to hear from a theorist – one who was deeply involved with string theory and championed it in his previous book, Three Roads to Quantum Gravity – that all is not well in this closeted realm. Smolin argues from the outset that viable hypotheses must lead to observable consequences by which they can be tested and judged. That is, they have to be falsifiable. Newton's theory of gravitation, for example, could later account for the orbit of Halley's Comet – not just those of the Moon and planets for which it was originally formulated. But string theory by its very nature does not allow for such probing, according to Smolin, and therefore it must be considered as an unprovable conjecture."
Hmm, I may give you that one. :-) Although I could split hairs and point out that at the time he made that statement he was no longer an advocate of string theory and instead was championing a competitor to string theory (loop quantum gravity).
And when Smolin released that book it was roundly attacked by the advocates of string theory for its claims of string theory being unfalsifiable.

So, of course, the generalization in the article is still blatantly false, but touche on sort of answering my challenge. :-)
