They were not even proven wrong. The core hypothesis of string theory is unfalsifiable, at least if we find another theory at the same scale that is then verified by experiments. If it turns out that there is nothing significant "beneath" the Standard Model (ie that General Relativity and Quantum Mechanics can be unified with only minor extensions), then string theory may remain unfalsifiable forever.
