This paper was not widely noticed back when it was written in July (both inside and outside the theoretical physics community) and still has not been accepted in a journal.
In fact, it is rather unfortunate but most of what Stephen Hawking did in his latter years has been highly speculative; perhaps food for thought for other experts, but not worth reporting about in the mainstream media since it is (in my opinion) very likely to be wrong.
I apologize for not debunking this paper with more detail but a scientist can spend a lifetime doing so... However I can make one falsifiable prediction (like a true physicist): the serious news media will not report on this.
Chapter 13 of (the second edition of) that book also revisits the original paper from a modern viewpoint and overlaps with the current article. For example, both the book and the article mention the similarity with the state transformer, introduce instances of 'functor' and 'applicative' before the 'monad' instance, and discuss the 'alternative' instance.

So I think I should interpret your criticism as saying that quanta does a poor job in maintaining rigor while trying to explain advanced topics in mathematics and theoretical physics to a wide audience. My impression, on the other hand, is that their reporting on these topics beats similar publications hands down. I am therefore happy to recommend it to interested laypeople, for example to my (few...) friends outside of academia and to people here on HN.
By the way, I hope you realize that these two viewpoints are not completely orthogonal.
Also, sigh. If you dig deep into the dark corners of the internets then I am sure that you can find fake anything. Focus on the beauty and the truth, people. For example:
[1] LIGO continues to work beautifully, as evidenced by its second detection of gravitational waves back in June: http://news.mit.edu/2016/second-time-ligo-detects-gravitatio...
[2] A fun but highly speculative 'bump' in the LHC data, which will probably go away but is fun to think about: https://profmattstrassler.com/2016/10/21/hiding-from-a-night...
[3] New precision results from a nice little experiment done 'on the side' at CERN: https://press.cern/press-releases/2017/01/cern-experiment-re...
[4] Or just a very accessible overview of particle physics in 2016: http://www.symmetrymagazine.org/article/2016-year-in-particl...
(a) If these models break down somewhere I would expect it to happen under much more extreme conditions and not with a 'table-top' experiment like this one.
(b) As far as I can see, giving up momentum conservation is not a feature that we can simply 'bolt onto' the existing models. It would require a radical rethinking of the very foundations of our current physical models.
So my personal attitude is that extraordinary claims require extraordinary evidence and this paper is not remotely convincing.
This experiment reminds me very much of the faster-than-light neutrinos. The authors of that experiment also seemed careful enough to not overstate their claims but this did not prevent a massive public interest in an ultimately debunked result. I expect the results in this paper to go the same way.
You are stretching the meaning of my comment. Did you know that he published three papers in the three years before getting hired in Edinburgh in 1960? I only pointed out that (on any 'time horizon') his scientific productivity after 1964 was basically non-existent.
In fact I agree on some level with a lot of the comments here, including yours. I just think that Peter Higgs is not the right example to justify the cause.
> and unless we collectively realize that we can just lay back and don't need to actually compete, it won't get any better.
And therefore, sadly, it won't.
The quantum field theory is then the one living on the worldsheet of the strings, it is the one that describes their embedding in this peculiar space. The monster group turns out to be a symmetry group of this field theory.
This is all conjecturally related to quantum gravity (according to Witten's paper) through the so-called AdS/CFT correspondence which states that field theories are sometimes equivalent to theories of quantum gravity. It has its problems and it remains to be seen if it is really true. (AdS/CFT is fine in itself, the trouble of the conjecture is whether it holds in this particular example.)
A word of warning based on previous experience: this is highly technical stuff and what is mentioned here are just words. Please don't think you can make contributions to this field without seriously studying the equations.
