> Lee Smolin (author of The Trouble With Physics[1]) lamented that your career in physics is essentially dead unless you went into string theory, and pursuing quantum gravity could lead to conflict with pro-string peers.
Famously, yes. But although that may have been true to a first approximation, it ignores the fact that alternatives have never been completely taboo.
The primary one in recent decades was Loop Quantum Gravity, and the related Spin Foams that my friend John Baez worked on for many years.

LQG hasn't won the day, I'm just mentioning that it was an alternative to String Theory that didn't ruin careers.
