"I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes"
About this Quote
The subtext is a recalibration of what counts as success. In high-energy theory, where experiments are scarce and the math can outrun measurement, “truth” can’t be the only metric. Witten is implicitly defending a broader epistemology: judge a framework by the tools it invents, the connections it forges, the problems it makes tractable. String theory’s most durable achievements have often been of that kind: dualities that translate intractable questions into solvable ones; holography, which reframes gravity in terms of a non-gravitational quantum theory; black hole entropy counts that turn a metaphysical abyss into a bookkeeping problem.
Context matters: this is a veteran speaking after decades of hype cycles, criticism, and genuine breakthroughs. The phrasing (“I wouldn’t have thought...”) is modest on the surface, but it signals a deeper point about intellectual ecosystems. Even a failed grand unification project can function as an R&D lab for physics itself, generating a new language that retroactively clarifies what we thought we already understood.
