Is a bunch of people trying to hack on physics to bridge GR and QM. There are a couple different ways to do this. Strings are one, loop quantum gravity is another.
Right now, everyone is still in pre-release debugging, not even beta-testing. It's ALL VAPORWARE. Complicating things, as always is money - grants, funding, publication, as well as ego and rep - appointments, tenure, etc. The truth will out eventually - the theories WILL mature and develop; testable, falsifiable hypotheses will be formulated - patience, grasshopper.
What I'd like to know, now, is who's the "Home Brew Computing Club" of this mess and who is the "Bill Gates writing bitchy whiny letters complaining about shit"?
Witten and Greene I've heard of. String theory and string theoreticians are carrying the day (in political / "marketing" terms) in the academy. Who is losing and bitching? Apart from their economic incentive to bitch, should they be?
