Worth noting this is ultimately the problem with string theory: String theory does provide a suite of mathematical tools which can solve real physics problems and give valid answers but they're known physics problems that can also be solved with other tools. To be useful as a theoretical framework it always needed to be able to predict something which only string theory could - as a "more accurate view of reality". Which is the same problem here: you've got to make a prediction, an accessible prediction, and ideally also not introduce any new incompatibilities.
