So for example from the current thread:
(someone with training in the field): "It makes sense, it's important and it's a possibility worthy enough to be explored."
versus:
(admittedly uninformed person): "As a layman from a distance, [...] it's total garbage."
Is there any nearer term benefit that may come out of string theory ? I am honestly curious. Somehow I find it hard to believe that so many very intelligent people are chasing something misguided.
That said, we're not devoting the kind of resources to string theory that we devote to engineering ready problems. Probably somewhere in the ballpark of $10M/year worldwide funding provided by various governments, with a similar amount provided by private donors. This is rounding error. In the US, we spend about 10x this on the National Endowment for the Arts.
You can make an argument that all money spent on extensions of the Standard Model (and there are a lot of them besides string theory) has been wasted. But string theory at least has taught us far more about the structure of the mathematical models we use to describe physics than any of its competitors. This is why people continue to study it, even in the absence of experimental confirmation.
