Probably more for all the Chinese bots here, since this video has apparently been overdone at Sciforums.

VIDEO EXCERPTS: For decades there have been two different schools of thought in the field of loop quantum gravity, one of which, represented most prominently by Lee Smolin, has insisted that the theory can be tested with upcoming experiments. The other, represented by Carlo Rovelli, is fine with the theory being untestable for all practical purposes. So now the situation is that either the theory is falsified or it’s not falsifiable.

It’s exactly the same crap as with string theory, and supersymmetry, and inflation and dark sectors and many other research bubbles in the foundations of physics. It’s mathematical fiction. It’s nothing to do with reality anymore. I don’t understand why people get paid for doing this, and I say this as someone who once got paid for doing this.

[...] I recently heard Eric Weinstein say in a video that we are seeing the beginning of a collapse in the foundations of physics, because it’s so obvious now that string theory was a huge mistake. I think you’re wrong Eric. This will keep on going and going until physics is entirely dead.

[...] Everyone who works on this just repeats arguments that they all know to be wrong to keep the money coming. Because let’s be real, these people sit on cozy tax-paid positions with no other task than producing useless papers that no one understands and therefore no one dares criticize...

t’s like string theorists never actually proved that their theory is indeed finite and solves the problem that they claim it solves. They just gave up on trying to prove it. It’s another one of those inconvenient facts that no one ever talks about.

[...] Oh, and Carlo now says that I just don’t understand the physics of his wonderful theory. Fine. That’s possible. Maybe I just don’t understand how great loop quantum gravity is. But the fact is, this so-called research has been going on for 4 decades. And what’s come out of it, besides papers? Nothing. Nada. Niente. It hasn’t taught us anything about nature whatsoever. If you look at the arxiv and check what people in loop quantum gravity work on these days, it’s basically still the same stuff they did 20 years ago. History repeating. No self-correction. No progress.

And it’s like that in string theory too....
