How Crackpots and String Theorists Attack Einstein's Relativity

According to Nima Arkani-Hamed, crackpots attack Einstein's relativity in the following incorrect way:

Crackpots (20:21): "Everything old is wrong. Einstein was an idiot. You guys all believe in deep authority. No one is brave enough to challenge Einstein." http://www.cornell.edu/video/nima-ar...ntal-physics-1

The only correct way to attack Einstein's relativity, practiced by string theorists, is as follows. Einstein's spacetime is wrong, doesn't exist, and should be abandoned, but the underlying premise, Einstein's constant-speed-of-light postulate, is gloriously true, Divine Einstein, yes we all believe in relativity, relativity, relativity:

Nima Arkani-Hamed (06:09): "Almost all of us believe that space-time doesn't really exist, space-time is doomed and has to be replaced by some more primitive building blocks." https://www.youtube.com/watch?v=U47kyV4TMnE

Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by." https://www.edge.org/response-detail/26563

What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..." https://www.edge.org/response-detail/25477

"Rethinking Einstein: The end of space-time. It was a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so space-time - the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter - was born. It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage." https://www.newscientist.com/article...of-space-time/
