That string theory is already compatible with everything we know about reality is a titanic achievement.

If you think it's not, go ahead and list all of the other alternatives that also have a hope of unifying gravity?

Except that string theory requires supersymmetry, and the latest LHC results are not happy for supersymmetry.

As for other unifying theories, loop quantum gravity is somewhat popular. And Wikipedia has a nice list of alternative theories: https://en.wikipedia.org/wiki/Quantum_gravity#Other_approach.... String theory is far from the only game in town, despite what string theorists would have you believe.

String theory is in fact compatible with a large number of possible realities. That's the problem.
