Post String (M-) theory as quantum gravity is officially dead
One, see K.C. Cole article (on September 15, 2016): "The Strange Second Life of String Theory", see https://www.quantamagazine.org/20160915 ... cond-life/

Two, the diehard String (M-) theorist states, see https://4gravitons.wordpress.com/2016/0 ... strappers/ :
One, String theory has been called the particle physicist’s approach to quantum gravity. …
Two, When people talk about the failure of string theory, they’re usually talking about its aspirations as a “theory of everything”.
Three, The quirky thing about science: sociologically, success and failure look pretty similar. Either way, it’s time to find a new project.
That is, the string-theorists can still be {entanglers or bootstrappers}.

Three, on September 27, 2016, Sabine Hossenfelder (Theoretical Physicist) wrote an article: {What do physicists mean by “quantum gravity”? http://backreaction.blogspot.com/2016/0 ... an-by.html }. She wrote: {Physicists refer with “quantum gravity” not so much to a specific theory but to the sought-after solution to various problems in the established theories. … Physicists are presently pursuing various approaches to a theory of quantum gravity, notably string theory, loop quantum gravity, asymptotically safe gravity, and causal dynamical triangulation, for just to name the most popular ones. But none of these approaches has experimental evidence speaking for it. Indeed, so far none of them has made a testable prediction.}

Massimo Pigliucci (very prominent philosopher/biologist) was a speaker at the Munich conference (Why Trust a Theory), see https://platofootnote.wordpress.com/201 ... ry-part-i/ .
