It's good for situations where the bottleneck is sheer processing speed---math problems on standardized tests, for instance---but many problems in the real world have bottlenecks of perspective, or information. I'd have been a good medical student, but probably a terrible doctor.
I've hammered a lot of screws in my time.
I had been stocking groceries for about a month when I had an interesting conversation with two senior employees (20 or 30 years a piece at the job). One of them was telling me that I was doing well but that I needed to start going more quickly. The other saw the mistake in this advice and said something along the lines of, "Well, hold on, though: you know speed comes naturally with practice. He'll get faster once he knows the work better." The other senior employee thought about it for a second, and then agreed in full and admitted their mistake. As a consequence, I focused on learning my work well instead of trying to be fast—and I became one of the fastest stockers in the store within a year.
I don't think you can will speed to happen, or train it specially: it's a consequence of already having solved the problems at hand before, already knowing the solutions and not needing to figure things out in the moment.
So you aren't going to 'get sharper'; you'll just learn particular domains better or not, and the ones you know better you'll be perceived as sharper in.
Hmm, I see I got downvoted. Whatever.
When you start out, you are told to practice your scales by making sure the notes are clean and even in volume.
Doing it fast comes later.
I was going to say something like this until I saw everyone else saying the same thing. This leads to my theory, and some facts.
The geek population has a high percentage of mild autistics. I firmly believe my lack of social skills, and slow thinking, is related to a mild amount of autism. I can't play any games involving fast thinking but I have reason to believe I'm a genius (just saying).
I heard an interview on NPR with Temple Grandin, an autistic author (I highly suggest reading her stuff). One thing she said was that a high percentage of functional autistics were programmers (I know this doesn't mean the converse is true).
She gave a quick single-question test for people to roughly judge autism. I answered on the autistic side. I was at a company lunch with about 5 programmers and 5 marketing people. I asked everyone the question and all the programmers gave the autistic answer and all the marketing people gave the opposite (I know it was probably a bit of coincidence and only one data point).
The test is "Think of a church steeple". I will give the meaning of the answer in a day or so. You need to think without knowing what any answer means.
EDIT: I figured out a way to give the answer without prejudicing your thinking. Don't read the answer below until you have thought of a steeple. The answer is written in reverse.

I confess my original answer was to remember that old kids song where you make a steeple with your hands and then flip them to see the people. I then thought that I don't actually know what distinguishes a steeple from a plain roof.
Still, that is straying. I'm curious what the original aim was.
as far as what the aim was , I'm not sure exactly. just nice to know people who experience the same thing as me and then musing on it and rambling like i always do
Per the word choice in suffering, I know it is the common word to use for things like this. I'm sure I use it some myself, I just try and avoid it when I can. I have no doubt this affects my methods of thinking. But, having never known the other ones, really, I can't say much else about it.
It is funny how I always thought of myself as just not visual. Never really considered it was because I don't see as much with my eyes closed, per se.
The really mind blowing experience for me, is how I can find things I did in the past and have almost zero memory of the visual aspect of it. I knew I spent time on something, but I don't remember how it looked as a finished thing.
Thing with churches is I never really pay attention to them so I'm also pretty sure I would've thought of my own abstract version of it. I also have a lot of trouble navigating according to landmarks, any buildings or details. I can't remember directions or the path I came from when going again or reversing. I eventually do remember, but compared to people I know it's a lot worse. Everyone else seems to know where church with this and that name is, but I do not.
I spent about ten minutes searching with the keywords "high functioning autism", "autism employment", "autism programmers", etc and could not dig up any studies substantiating the claims you've mentioned. This is not to say you're lying - I believe you actually did pick them up from somewhere. But I'm deeply skeptical of their clinical veracity and empirical provenance. Given how polarizing autism can be and how difficult it can be to research, I consider it harmful to be confidently describing "theories" like yours without much real support for the claims involved.
In particular, I would strongly advise anyone reading this to resist the temptation to self-diagnose or self-identify (one way or the other!) based on a strange question designed to see if you actually think of a church steeple. If you believe you may be autistic, personally see a professional and try not to read into the popsci promulgated by radio interviews.
Also in defense, I was careful to word everything as suspect, not fact.
