Well, nuclear power (and nuclear weapons) had their origins in a bunch of esoteric equations at one point, too.
One possible outcome of explaining gravity and a string universe is coming up with unlimited energy or faster than light travel...
Or it could be a dead end, meaning nothing like the fruitless search for a “Northwest Passage” in the 1600’s. Still need to explore and try to push physics... The old adage is “today’s theory, tomorrow’s engineering project.”

By this logic, any arbitrary set of mathematical equations is worth pursuing since it might end up producing nuclear power.
Those of us who can actually do the math understand that the number of potential equations is infinite, and that any one of them may yield fruitful results is infinitely small.
The thing about those theories that amount to something... they all have physical ties to reality. Not one was a purely mathematic construct without any such tie, the way string theory is. There is not a single thing in nature that can be shown to behave according to string theory or according to any set of rules like it.
