Most childhood prodigies don't end up being all that different from the average person as an adult, and of course no one's born with the knowledge of some revolutionary discovery in their head.
While all of us have things we find easier to do than the average person, short of a literal mental disability, we can build up skills in things we are not good at through practice. I used to barely pass in math class and didn't even understand the concept of negative numbers until 8th grade. A year of practicing daily for 2 hours after school, and my fundamentals had gotten good enough that I unknowingly derived a calculus-based solution to some problems I was stuck at, 2 grade levels before when I'd actually start learning calculus and got to skip a year as a result.
Similarly, I've been teaching myself to draw despite having been pretty terrible at it and discovering how 'deliberate' most professional artists have to be with practice and building skills.
I think it's pretty common for people to write off their inability to do something as just a lack of innate ability, when it's really just that no one really sees the struggle anyone famous for their work/skill has gone through to get there.
But there definitely is a wide variation in peak capability. I have been playing keyboard instruments almost my whole life, and while I can play relatively complex pieces, I've never gotten at the level of professional musicians, let alone the greats. It's true they wouldn't have gotten where they are without practicing, but practicing is just not enough.
But has the goal you've been aggressively working towards been to reach those levels? or have you been playing just for the enjoyment of playing?
Not to suggest that the latter is wrong, just interested in your actual goal. In teaching myself to draw (anime art specifically), I'm aiming to reach a professional level, but am not interested in becoming a professional artist. The only factor I've felt would limit my ability to achieve this is time commitment (since research is pretty time consuming already). I'm not interested in committing as fully to it as someone who makes their living off art, so I don't expect to match them in all ways. So, for instance, while I expect to eventually be able to match in terms of overall result, I expect to not be anywhere near as fast as a professional can be.
I'm confident that the technical skills can almost (e.g. disabilities) always be trained, given sufficient time.
Creativity/inspiration seems to be missing culturally. Consider for example Maths or Physics, where creativity is essential to internalize the material, but the teachings usually emphasize memorizing a few tricks to solve well-known problems and pass the year.
But even if it could be trained, there's 1) the luck factor 2) inborn quality variations. Some people just have it in their bones more than others, even if it manifests "just" as being more relentless in practicing.
That's to say, I mostly agree with you, but I'm curious as to how far we could reach with different teaching approaches.
Look, a lot of people throw their heart in soul into $FOO, and a lot of them give up or never succeed (if they can afford to keep failing) because they aren't getting the results, not just vice versa.
Slow and steady doesn't win the race against fast and steady.
