The error with this approach is that every single physics theory gets exactly the same criticisms.

You can take any of the theories that Hossenfelder would spend time on instead of the ones she does not like, and you would find (basically) a similar percentage of physicists saying it's a mistake to continue in this direction.

In other terms: for each physics theory, on 100 physicists, you have 5 physicists saying it is a mistake to continue working on it (number made up for illustration, and there is probably some variations, but you get the gist). You took one theory and found few physicists saying it is a mistake to continue working on it. You conclude, incorrectly, that it means this theory is fundamentally differently treated as any other theories.

(on top of that, it is unfortunate that Hossenfelder later screw up her image by doing way too much mistakes that someone reliable would not do)

And in the meanwhile you ignored Susskind, literally one of the fathers of String Theory saying "we need to start all over again"... :-))

    I did not ignore Susskind at all. I literally say "for each physics theory, on 100 physicists, you have 5 physicists saying it is a mistake to continue working on it". I mentioned the name of Hossenfelder, but you can replace it by "Susskind" or "Hossenfelder and Susskind", and the argument is as valid.

    As for Susskind, the fact that he was a main contributor is not a factor, on the contrary, what I had in mind is about the percentage of experts in the subject that later criticize the field. You have plenty of other examples in other fields: Shiffman on SUSY, Loeb on WIMP, Hirsch on applied fusion, ... or even Einstein on quantum physics ("Yes, I may have started it but I always regarded these ideas as temporary. I never thought that others would take them so much more seriously than I did.")

    Some outsiders are seeing a normal scientific process where people are continuously questioning the validity or the efficiency of things, and they start in their fantasy "look, they say it should not be done this way, it's the proof it's all wrong".

    Again, what we observe with String Theory is not at all exceptional. The reason it is "a big deal" is because of the populist message and the scam around "these physicists who stole the public money". It is a bit like "vaccines cause autism": it got some media attention, it resonated with the populist conspiracy theory of "the physicists know but they are farming money" and the anti-intellectual trend, and now it has become both some kind of cultural war and an easy way to farm views and followings and show themselves as "so rebel, so edgy".

    Don't get me wrong, I personally think that String Theory is overrated (and I was thinking that way before it was popular to criticize it). And the return of the pendulum means that it may now be in the edge side of the average. But nothing significant to pretend there is a particular dysfunction.
