Title: Where is string theory today?
Hard to talk about where we are today without saying where we’ve been. Different eras of string theory:
1968-74: Dual resonance era, ended with discovery of asymptotic freedom
1975-83: Quantum gravity Era, people pushing this idea were mostly ignored
1984-94: Unification Era, emphasis on CFT techniques
1995-1998: Duality Era, emphasis on spacetime point of view, and role of SUSY
Finally, we might be at the end of AdS/CFT era.
