This sounds like the reaction against "Fake News", "Fake History", etc.

What that really tells me is this is an area of study that the Establishment does not want you to follow so it will label it to apply social pressure to mitigate the effects & discourage people from following it.

The thing is, nature has a way of not caring what the Establishment thinks. It does care on a surface level, but it also conspires to cause the collapse of the socio-information paradigms that the Establishment creates.

Given we have a soup of information & no grounding central authority to give us "objective reality", we ought to utilize other techniques. I don't happen to know what these techniques are, but I suspect that it has to do with network models, cognition models, perspectives (physical & information), attention schemas, faith, complexity, patterns, language, etc.

You're right as far as you go, but actually nature doesn't care what anyone thinks. One thing to question is how the establishment got to be established. If it was primarily through physical strength, heredity, or persuasion (as is more true for the bulk of history), then they are no more likely to be right than a plebe (except that p(persuasive | true) > p(persuasive)). But it's more true than in most of history that the odds of being an elite are much higher if you can consistently make correct predictions about the world.

It's true that we don't have a central authority to give us an objective reality, but we don't need one either. Reality is there if only you choose to observe it closely. I think the best technique for dealing with the soup of information is to find bona fide experts with a track record of providing correct explanations and giving what they say more weight.

Knowledge is seen as dangerous by people holding power over others. It always has been (e.g. the apple thing). Therefore, in an age where knowledge is more readily accessible to a much larger number of people, it behoves the groups in power to somehow thwart its development. A good way of accomplishing this is to use mass media to make the signal to noise ratio as small as possible. Which is itself accomplished nicely by paid, conscious, agents and amplified by the growing hordes of individuals humiliated, rather than motivated, by their lack of knowledge. The true becomes a moment of the false, the real a moment of the fake. I believe that "spaces", real or virtual, rather than techniques will develop for knowledge to flow and grow.

This is a frustrating era for physicists. In the mid 20th century they were like gods, giving the world the atomic bomb and the semiconductor. Today many branches of physics are stuck. The cosmologists can't find "dark matter", and aren't even sure it's necessary. The string theorists have pretty but un-testable theories. The fusion guys can't make fusion power work. Quantum mechanics and general relativity still haven't been reconciled. And nobody has a useful handle on gravity. These problems have been outstanding for decades now, with some churn, but little progress.

(The bright spot is near absolute zero, in low, low energy physics. Lots of interesting experimental results from down there in recent years.)

The multiverse approach (the universe forks at every quantum event, and all those universes continue to exist, forking further) is the default you end up at given what we know now. Hawking once said it was "trivially true". But it's unsatisfying. It means most of the fundamental constants are arbitrary, for one thing. Then there's the anthropic principle (our universe works well enough to have life because we happen to be in a fork where the constants have values which make chemistry work). That's unsatisfying, too. This un-testable stuff is more philosophy than physics.

This, from a historical viewpoint, is a failure. From Lord Kelvin to Fred Hoyle, physics was about measurement and prediction. Theories which can't be grounded in experiment are of little use. Today's physicists are losers by historical standards. This has career effects. Los Alamos is a lot less prestigious than it once was, and there's been substantial downsizing.[1]

You have to dig down to the 2nd page of comments on his previous post about these articles to learn that when he says "multiverse" he isn't referring to the many worlds interpretation of QM:

It's very confusing and I can't help but assume he doesn't mind misleading people.

I think this assessment is magnificently incorrect. Over the past 30 years there have been very important experiments, many of which have reached the mainstream. This includes anything from the Higgs experiments to the LIGO experiments. What about things closer to the HN crowd, like communications infrastructure like the Internet?

The discovery of the transistor didn't bring an iPhone overnight. Same with many other scientific discoveries that had to go through a long engineering phase. I see a similar trend happening now with quantum computation, which has seen great leaps over the past 20 years and continues to accelerate in both academia and industry.

It's my opinion that, at least in America, we live in a less intellectually disciplined and intellectually favored society. Anti-intellectualism, even in nominally educated portions of society, seems to be on the rise. This unfortunately has the effect of making science look stagnant to the larger population, and unless there are gadgets of instant gratification that science explicitly produces, it'll remain somewhat obscure to folks uninterested in advancement for the sake of advancement.

As for the multiverse stuff, I'm not sure why you think that it has to do with the arbitrary selection of constants. The multiverse interpretation of quantum mechanics doesn't say "anything happens and it all happens in separate multiverses", but rather that—in simple terms—non-deterministic events like measurements bifurcate into separate universes. But QM still posits that the results of these non-deterministic events are each probable, and each obey the same laws of physics equally. In other words, it has a more "butterfly effect" on us, keeping physical constants as truly constants, not a "splitting of universal laws effect".

I think that the fusion guys think that they have made fusion work and are going to deliver it commercially in ~15 years (in ~5 years this claim will be either obvious or dead).

I think that the quantum computer guys think that they are about to deliver as well.

I agree about the lack of substantial progress, but for the record the standard many worlds theories still predict that most "constants" actually are constants; they're the same in every branch.
