The goal is to find e.g. Lagrangian, which consequences are in agreement with nature ... but calculating these consequences is quite tough - AI could generate required simulations, and it is already starting.

The question is where to search for such e.g. Lagrangian? There are already many people having own models developed for decades - AI could help to objectively verify with simulations - building kind of arena for models, to select the ones in the best agreement with nature, identify their best features.

After checking the already available physics models from humans, maybe succeeding would be also AI generated - e.g. combining what was the most successful in the tested models.

One can get grants in physics nearly only if being mainstream ...

Consa brings concrete arguments regarding g-factor, I still haven't seen any concrete explanation, only saying that it is fringe science because of criticism of mainstream ... but he quotes mainstream papers.

Mainstream censors non-mainstream, hence for half a century we are staying in place e.g. quantum gravity, there are appearing new problems ...

https://phys.org/news/2022-05-standard-particle-physics-brok...

The paper claims there are problems already with g-factor, could anybody explain why its objections are not valid?

Thanks, I will read, but generally beside e.g. the gravity problem, with increased accuracy there appear inaccuracies all over the standard model, so maybe it is worth revisiting QED? Are you saying the g-factor inaccuracies are not a problem?

https://phys.org/news/2022-05-standard-particle-physics-brok...

Indeed, e.g. of Dirac:

    “I must say that I am very dissatisfied with the situation because this so-called ’good theory’ does involve neglecting infinities which appear in its equations, ignoring them in an arbitrary way. This is just not sensible mathematics. Sensible mathematics involves disregarding a quantity when it is small – not neglecting it just because it is infinitely great and you do not want it!. ”
and Feynman:

    "The shell game that we play is technically called ’renormalization’. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It’s surprising that the theory still hasn’t been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.”

Your data is now written with ANS if using e.g. Apple, Facebook, Google, Linux, soon JPEG XL: https://en.wikipedia.org/wiki/Asymmetric_numeral_systems

This patent covers rANS variant which is used for example in https://en.wikipedia.org/wiki/JPEG_XL - if granted, only Microsoft will be able to make its hardware encoders/decoders.

Google is trying to patent video compression use of Asymmetric Numeral Systems

Asymmetric Numeral Systems ([1]) is entropy coding family currently replacing Huffman and arithmetic coding in data compressors, among others, of Apple, Facebook and Google, thanks to being up to 30x faster [2]. Its author has made it public to prevent pathology of arithmetic coding, which wide use was blocked by patents for many decades ([3], [4]).However, currently others are trying to patent...

I've meant special relativity.
If you restrict the speed of propagation of interactions (of massless waves), you nearly automatically get STR ... like in sine-Gordon model - speed of massive kinks becomes limited, and kinks are being contracted to zero while approaching this limit.
