You never know if learning calculus will make you discover new things that you might like to pursue. Also, you never know if you will need it or not apriori. By that logic, you shouldn't learn anything until you need it, wich I think would be a disaster.

Just as you will never know what you might have discovered if you used the time you spent learning calculus learning something else instead, of course. There is no magic formula to life.

> you shouldn't learn anything until you need it

Impossible. Simply existing as a functioning human means you are going to be constantly learning something. Not everything you learn will be useful, but that's also true of calculus. Not everyone finds it useful in the end either. You never know what will end up being useful, but you also can't learn everything.

The great thing about the curious mind is that you tend to be naturally drawn towards the things that are most useful for you. Those born most likely to do something with calculus already voluntarily choose to learn about it. You don't have to make them. The stereotypical druggy who has no interest in anything but getting high, who suddenly has his life turned around because you force him to learn calculus, is little more than Hollywood fantasy.

This framing doesn't fit my experience. Most kids, left to their own devices, would not learn arithmetic.

I know few adults that were forced to learn something as kids that regret learning it. Conversely I know tons of adults that, as a kid talked their parents out of being forced to learn something and as an adult seriously regret it.

I think it's hard to have the kind of meta-skills as a child, it's kind of hit and miss. (Ie discovery, learn what to learn, how to learn, make learning pleasant). As an example, music is one thing that works best if parents, siblings and friends are into it and you can do it together or if it's somehow ambiently present most of the time. But if it's something that you only go to lessons for, decided by someone else, that you don't enjoy etc - then it's often like pouring water into a dry well. Yet those mechanical even if less enthusiastic skills can then be useful later, if the inspiration comes, with a new social circle etc. Or similar with sports. In some families, it's more "present" in an ambient way. When waiting for something outside, the kids have some hockey sticks and a tennis ball lying around and just start playing, maybe with adults who also find it fun. Or talking with the family about the news in an analytical way: that person leads that party and they have these values, while that other person drives these other things. If you have these available then different kids are exposed to things and can pick up things they are more inclined to. I've read lots of mathematician and scientists' stories how Martin Gardner's problem books drew them in to the field. So parents exposed them but didn't force. And their exceptional inclination did a lot of work.

Unlikely. Too many things in life depend on arithmetic. Most people will learn things when they must.

What is more likely is that kids won't learn arithmetic before they need it and therefore may theoretically miss out on the aforementioned discoveries that are overlooked when one doesn't already have a foundation in arithmetic. However, most people never have such discoveries anyway. Those who do tend to be the type that would learn something like arithmetic just for fun.

> I know few adults that were forced to learn something as kids that regret learning it.

As a once child, if I didn't want to learn something, I didn't. Forcing someone to sit in a classroom where a subject is being taught, for example, is not the same as actually learning the material. So this is an obvious truism. Those who didn't want to learn something never did.

Yes but arithmetic is actually not intuitive at all, and you can certainly grow up to not know it. There's a lot of people who once grew up not knowing how to read, because they didn't go to school.

Children are still children, they very famously make poor decisions. Yes, not all children, but most. We have to mold and steer them, because for humans we come into this world as basically blank slates. We're not like other animals, ready to roll. We require decades of careful curation.

"for humans we come into this world as basically blank slates."

Can you source this? I thought we were pretty much expressions of our particular genetics and the biological human substrate we all inhabit. This is very much not a 'blank slate'. Every time I've tried to look into or steelman the blank-slate I can never come across hard science that backs up the assertion that we are all 'blank slates'.

Blank-slate seems to be more of a liberal idea then a scientific one.

Blank-slate as compared to most other mammals, who are often born with knowledge of how to walk, feed, or even hunt. These skills usually come pretty quickly, most mammals have their young on their own within a year. Humans can’t even walk for a year. Many other mammals walk on their first day.

We also have case studies that if humans are not taught language then they won’t, and can’t, speak. Genie comes to mind.

▲win311fwg 7 hours ago | parent [-]

Genie could't speak because she was deprived of exposure to normal human interaction, not because of lack of being taught. It is apparent you've never been around a child because otherwise you'd have quickly recnoized that most of them do speak before anyone tries to teach them how.

I’ve obviously been around children, and I do qualify speaking to children as “teaching them how to speak”.

If you speak math problems to your child you are… wait for it… teaching them arithmetic. That’s what teaching is.

Arithmetic is not something that just naturally exists in the world, it’s a purely human construct. It does have to be taught in one way or another, otherwise people won’t know it. And, unlike language, I seriously doubt parents are just speaking arithmetic randomly in conversation that often. Your kid most definitely will not just “pick up” arithmetic.

In fact, I doubt a kid would even pick up language if you never spoke to them directly, and instead they just heard bits in passing between adults.

Exposure to something and being taught something are usually recognized as being quite different, but it is clear now that you just want to play a game of semantics, so we can put and end to that.

> I doubt a kid would even pick up language if you never spoke to them directly, and instead they just heard bits in passing between adults.

Kids not being able pick up on language by listening to a recording of adults speaking about some random thing is supported by the research so there is likely some validity to the latter half of your claim, with some assumptions about what you mean about "heard in passing", but the research also strongly suggests that kids can pick up on language if those adults are surrounded by additional context. For example, if adults in the same room were talking about a visible object in front of them then the research suggests that the child would be able to pick up the language even when not directly spoken to.

Why do you doubt the research?

> Yes but arithmetic is actually not intuitive at all, and you can certainly grow up to not know it.

If you are in a situation where you don't need it, sure, but if you don't need it then who cares? I get the nebulous "but what about the discoveries you are missing out on", but the type of people who wouldn't learn something like arithmetic for fun also never find discoveries anyway, and never would even if you could force feed them all the knowledge of the world. That argument really doesn't apply to most people.

> Children are still children, they very famously make poor decisions.

Not quite. What children are most famous for is that they won't learn until they want to. Poor decisions, implying that they could have made good decisions if only they would have listened, are the outcome of them not learning even when you tried.

> We have to mold and steer them

There are deadbeats in the world, sure, but for the most part that just naturally happens at least up until they hit the rebellious teen years. Kids want to be by your side, watching, learning. We wouldn't have made it as a species if this didn't occur automatically. Like I said before, you cannot exist without learning things constantly.
