Einstein spent his later career trying to reconcile general relativity and quantum mechanics. He failed. So has everyone after him. It's not about Einstein being old. It's that it's a really hard problem.

Not a physicist, so this may be a dumb question… but do we even know for sure it’s a problem with a solution?

Well, the universe does something with extremely small but extremely heavy objects, unless you think that merely creating that situation will cause the universe to cease to exist.

It should be pointed out that the math of spinning black holes which Einstein needed to reconcile GR and QM wasn't discovered/invented until the 1980s. And we still haven't really checked to see if he was on to something. A big part of this is that the young have the energy to spread their ideas. The old often don't. That has as much to do with these things as being right or "on to something".

TFA also refers to just Einstein's 1905 papers. He published general relativity 10 years later. And after GE he contributed e.g. stimulated emission, Bose-Einstein statistics, Einstein-de Sitter cosmological model and the EPR paradox, among lots of other stuff.

"downplays that Einstein was pivotal in emerging the field in the first place."

Indeed, its a pretty easy case to make the Einstein has more to do with QM as it currently exists than Bohr does. The major interesting work on QM after the 1960s or so is entirely dependent upon Einstein's work on QM and locality. The entire narrative in fact comes from Bohr's hissy fit after Einstein pointed out that QM is non-local and that seems very wrong.

I feel like many younger people still listen to music from the 70s, 80s, 90s, 2000s etc, as an exception (?)

That's in the rule - for them it's "just a natural part of the way the world works".

Ah I misunderstood; my mistake!

I don't know about number 3. As a 53 year old Gen X'er, I still haven't come across things that see against the natural order. The main things I don't understand are things like the Humane AI pin, which didn't seem against the natural order, I just didn't see the appeal or usefulness of it. Maybe it just doesn't seem like there is much new being invented.

> I still haven't come across things that see against the natural order. So many people these days spend hours watching short-form videos spray endlessly from a screen while they stare dumbly at it. They aren't even picking which videos to watch, just letting the algorithm do it. Every time I see someone doing that, I just absolutely cannot relate to what's going on in their head at all. I'm certainly not above watch…

I don't want to defend short-form video feeds too much, but "They aren't even picking which videos to watch" is overstating it. Essentially nobody behaves like: watch 100% of a video, swipe, watch 100%, swipe. The expected behavior is that you swipe away if you're not interested, which is often done within a fraction of a second. Accordingly, Tiktok's content selection algorithm heavily weighs watch time as a signal of interest in related content. That actually can create a bit of a perverse incentive; if you linger on a video long enough to report it (as in for a TOS violation) or to click the "show less like this", it can lead to being shown more videos like that.

In many ways, TikTok is kinda like channel surfing. Watch a few seconds, next channel, watch a few seconds, next channel, oh this is interesting, sure I'll watch a "How It's Made" marathon.

Now consider that the density of an atomic nucleus is oddly similar to the density of a black hole. And this was the path Einstein was following. Too bad you need computers to study it because of all the differential equations.

Seeing what came later with gauge theories and more speculative stuff like loop quantum gravity, you can't blame Einstein for thinking that the theory of everything might take the form of a set of field equations for a connection. Math was just too hard, and the answer probably doesn't look like that after all.

I found Thomas Kuhn's "The Structure of Scientific Revolutions" helpful on this topic. https://en.wikipedia.org/wiki/The_Structure_of_Scientific_Re...

I was shocked that the article did not mention Kuhn as the source for the two paradigms. Has he been forgotten already? And of course if you haven't read that book, it's insightful and easy

It’s almost like a corollary to the Douglas Adam’s principle referred to in the article - if there’s a theory about social behavior formulated before you’re born, it’s fair game to reformulate it.

This is my understanding as well. What the article described has been cannon for almost a century, but it may not be an accurate representation, and we still don't have the answers to address Einsteins' concerns.

(Article quote in question: "But toward the tail end of Einstein’s life, he argued strenuously against the concepts undergirding the emerging field of quantum mechanics, the ideas that are shaking up physics yet again and may lay bare even more of our universe’s mysteries.")
