EDIT: FFS why does this subject always get people frothing at the mouth before they even read the main point stated, only to go on and accidentally agree with it eventually? Pls read first before getting mad at stuff that I explicitly argued against.

EDIT 2: OK apparently there's still miscommunication, and I think the 1st edit somehow made it worse. When I say "useful" I put it in scare quotes on purpose and as I clarify in the 1st, 4th and 5th paragraps, it is NOT about value but about practical/technological utility.

I originally posted this on R*ddit to an audience of math nerds (so be warned that it is written with reddit STEMlords in mind) because there was a relevant convo going on and it would be fun to also have it here.

Sure, there is a lot of modern math that is practically useful, but the majority of pure math really isn't "useful' in any way, shape or form for now, and probably won't be any time soon, possibly forever. Like, even areas which are apparently "useful", like computer science, is full of things that have absolutely 0 practical utility and are solely of academic interest. Whether P does or doesn't equal NP doesn't really matter to anyone doing practical work. People wouldn't get upset about their discipline getting slighted or whatever if this stupid idea that scientific research should have "practical application" (which generally means "someone can sell it for money") hadn't proliferated, starting from schools.

Even when someone finds an "application" through some kind of far fetched (or not so far fetched) reasoning, it's some application to, like, highly theoretical physics that may or may not actually have something to do with the real world, and even if it does, it is only relevant in extremely niche experimental circumstances to the extent that it can't ever conceivably lead to technological progress. And even IF it does, sometimes it's just progress relevant only to more research about more stuff without application.

So even then you have to resort to saying something like "the result is not useful but maybe one of the methods used to prove it can be used for something else", and then that something else turns out to also not be useful but again "maybe one of the methods used to find that something else is useful for another something else and that other something else is useful for another other something else and then that other other something else has a practical application that is only relevant to research, but then maybe that relates to some other other other...", etc and it gets kind of silly. That or someone says something abstract like "it's useless now but it may be useful some time!". Maybe. Or maybe not.

In the end of the day the same arguments could be used to justify anything being useful via some contrived butterfly effect style conjecture. This of course is usually done because otherwise people can't get grant money otherwise, governments demand that research will produce results they can use to blow up people or sell stuff. Also the result of a bad educational system that emphasizes this kind of "usefulness", which therefore renders it unable to convince students that something is worth learning unless it is "useful". Of course "why should I learn this if it's not useful to me" is a very valid concern of students, but the problem is somewhere else. First, schools DON'T really teach any of the stuff that is useful and interesting to most people. If they did, then math would get a lot less attacks on that front. Schools teach with 30% of the students in mind, the ones who will really apply the things they learned. The other 70% can just go to prison or whatever as far as the educational system is concerned. Second, schools are very boring and antagonistic towards kids and since kids are miserable learning stuff, they need extra justification to learn them. Third, the schools themselves teach kids to think like that so it's no surprise that they do. Fourth, school math mostly sucks and is super boring for most people.

So yes, most modern pure math is indeed "useless". That is not the issue. The issue is, why does this matter? Why is it bad? Should it be bad? I don't think so. It's a false idea that gets perpetuated at many levels starting from school. But then there is the issue of mathematics being very exclusionary and distant from most people, which makes it harder for them to care, which brings us to the issue of outreach but whatever, that's a different matter.

      I'm gonna share an experience I had.

      When I was a 12yo kid, for around two hours of my life, music actually felt like you said, it didn't have any meaning or emotion, barely rhythm.

      Then I had a horrible migraine and the next day I was back to enjoying music.

      From this perspective of having experienced both, it really isn't a delusion.

          Yes, that's how I felt in that brief period of time, but before and after I could decode emotion and some meaning from it.

      Wtf is delusional about getting a feeling out of music lmao

      Most people aren't lying about feeling something because of prayer. Some do lie about it because they have ulterior motives. But generally people do get a feeling out of it because it makes them feel hopeful, it gets things out of their chest, they feel they connect to God and it is a moment of introspection. "But God is fake" cool, that's entirely irrelevant.

      With music there isn't even a structure above that can be true or false. You don't feel something out of music because you are "tricked" into believing something false. Like, perhaps you don't feel anything but that's not because you are right and they are wrong. It's just that for whatever reason it doesn't get you, which is way, way more unusual than the opposite.

        The analogy of prayer to music/art is that these are all things that are incredibly boring and pointless, but which society says are good, meaningful, and vitally important things.

        As far as prayer, “God is fake” is pretty relevant, because it means that most people aren’t really experiencing anything when they pray. It makes the most sense that they’re lying about getting anything out of it because of social stigma/norms. Not accounting for things that alter experiences like schizophrenia or LSD.

          Yeah because you can only experience a feeling if God makes you.

                      Doesn't mean they're lying if they feel something. It's called having emotions.

                            idk, but the experience they’re claiming isn’t real so the emotional response sounds made up too.

                            like suppose you told me you were very excited because you won the lottery. but then I find out you didn’t win the lottery. I would think that you probably weren’t excited about winning the lottery either.

                            e: the experience of talking to god

                              Have you considered that perhaps people who pray don't all claim they had supernatural experiences, but simply that they felt good?

                                No, I was neglecting that group as I’ve never met or heard of anyone like that, and it seems like a contradiction in terms.

                                It’s pretty implausible that someone would feel good from intentionally boring themselves for no reason. Just going off own experience and empathy.

                                      I mean I am honest, it's you who for some reason thinks everyone is lying to you about having emotions. You know, perhaps not everyone is lying and maybe your sense of empathy is just kinda out of whack.

It doesn't matter if God is literally talking to someone, that is not the experience. The experience is merely an emotional one. It is feeling like you are approaching God, which they believe exists. Just like someone can feel all sorts of ways thinking about someone they love. Obviously you have some issues empathising with people and understanding emotions and that's alright, but maybe you shouldn't assume other people are lying about it? Like, I'm not expecting you to understand this if you can't understand how someone can feel emotion from music, which is, like, one of the most universal emotions humans can have.

You’re downplaying it like they claim to just feel good from the act of praying, but that isn’t what they claim. Since this near universal experience isn’t real, why can’t another be fake.

                              like suppose you told me you were very excited because you won the lottery. but then I find out you didn’t win the lottery. I would think that you probably weren’t excited about winning the lottery either.

                              This comparison only works if you think they didn't win the lottery, but they think they did. So it makes sense for them to have an emotional reaction because as far as they're aware, they did win!

                                  People can have mistaken or unproven beliefs, and real reactions based on those beliefs. I would be really excited if I thought I won the lottery. People really believe in God when they pray.

                                    Would you be excited about winning the lottery if you knowingly didn’t win the lottery? Would you feel awe and wonder at God speaking to you if God didn’t speak to you?

                                      Yes, I can get excited by imagining all of the things I could do with the money from winning the lottery, knowing I haven't won. Yes, I can feel a sense of awe and wonder by putting myself in a reverent spiritual state without hearing a voice or detecting any supernatural change in my physical space.

                                        No, that’s different. That is knowingly imagining these things.

                                        I’m talking about someone who claims to experience these things in reality, but doesn’t.

                                          There's not as hard a line between imagining something and believing it as you're insisting. Wanting something to be true, and thinking they're true bleed into each other. I haven't won the lottery, but I personally have plans for what I would do with that money if I had won. I don't even play lottery? I can also hear voices in the silence, if I'm listening for them. I can concentrate on ambient noise and hear speech, even when I know it's just traffic or wind.

                                          Perception to belief to emotion is not a one-way street. Emotion can affect perception, perception can affect emotion, belief can affect perception.

                                              That's not a different camp. I'm not describing an unusual situation here but describing common human behavior as it appears, as people describe it for themselves. You're making an extraordinary claim, that everyone, billions of people, are lying about prayer and music (and the lottery), so you can't generalise your perspective but individualise my perspective when I'm making an ordinary claim. These are normal, typical, everyday things.

                                                what I’ve proven is that it’s really not an extraordinary claim that billions of people are lying.
