I think there are many questions where it’s very easy to convince yourself the solution is obvious after you’ve been shown it, but it’s less obvious for someone who is taking the time to try to figure it out on their own.
I teach college math courses (usually around calculus-level), and for every exam I give I will write a practice exam to post online a week before, and I’ll devote the lecture prior to the exam to reviewing those problems. I try to make every problem that appears on the exam very similar to one that was on the practice. The students who attempt the problems before the review session, even the students who get incorrect solutions in the process, will bulldoze their exams and will say it was essentially identical to the practice, while the students who just watch me give the solutions and copy down what I’m writing will tell me the practice was easy but this was barely similar at all.
When you see an obvious solution immediately, you completely bypass seeing potential stumbling blocks which might have tripped you up.
I was trying to use an example from personal experience to illustrate the benefit, but my point is that immediate answers wasn’t an option not too long ago, so curiosities you actually did want answered would necessarily have that delay. Being able to learn things well in spite of this shift is becoming a skill not everyone has. It’s something that needs to be nurtured, and it’s now easy to neglect, which really can affect everyone, although obviously some attitudes and lifestyles will be hit harder than others.
Something of a tangent but honestly I hate the way academia works here in general and I resent my role in contributing to math being used as a barrier to a better life. Unfortunately, I do need a career of some sort and there are worse things I could be doing. So I play by the rules well enough to keep my job and just try to do my best to be understanding.
I didn’t even enjoy math myself until I took an analysis course because I thought a math minor would help with job prospects. I always had an easy time with math and when I took analysis I got a D the first time and barely scraped by with a C the second. Math is actually interesting when you feel there’s creativity required in problem-solving, but it’s not reasonable to demand that in a lower-level math course because it doesn’t mesh well with a course existing primarily as a roadblock for students.
A hardworking student might still struggle to develop that creativity quickly enough to get through the course unscathed, which is fine if you’re enrolled because you just want to learn, but not fine for students trying to get good grades or at least pass everything to get through as quickly as possible. A student might have the crazy idea that failing is a financial hit or something. The result is you’re simply put through a grind until you voluntarily take on a course beyond the calculus sequence.
What I’m getting at is that I think your complaints all stem from the fact that, in spite of what we’re all forced to pretend, education is not the main purpose of academia.
