”The mechanical skills of wielding a pencil or mixing paint are almost trivial”

Trivial? Painting a single shape everybody knows got Giotto a job (http://theorbitbrown.com/site/the-perfect-circle/)

There are huge differences between humans in drawing ability and training.

But yes, in the case of these drawings, it seems the main difference is that many people apparently have never looked at a bicycle frame. I expect that to be somewhat different in countries where bicycles and people repairing their own bicycles are more common.

The Giotto story is almost certainly a myth. It's also largely irrelevant; anyone can draw a perfect circle in two seconds with a pair of compasses or a piece of string.

There are huge differences in drawing ability, but going from "I can't draw" to "I can draw quite well" takes days, not years. Becoming a confident and capable draftsman is a skill that anyone can learn to a surprisingly high degree of proficiency in a remarkably small amount of time. Most of us won't become Albrecht Dürer, but we all have the innate capacity to draw well if we simply understand the process.

Only if you consider a messy "chicken scratch" style good. I can draw things that look acceptable when you blur your eyes enough (which is indeed easy to learn), but I wouldn't claim to "draw quite well" unless I could do it with clean lines, which takes years of practice. When evaluating difficulty of a skill it's more usual to measure by difficulty of mastering it, not difficulty of getting beyond the very basics, and by that measure the mechanical side is much more difficult than the visual side.

here's a pro tip that I learnt in the animation scene

1. grab a wooden pencil 2. hold it so that the broad side of the lead touches the paper, not the point - you'll get a broad, pale grey line 3. rough in your drawing this way 4. when you feel like you have a solid drawing, switch to the tip of the pencil (or to a pen) and trace the lines you made in step 3

This will make it a lot easier to have a nice, clean drawing done with bold, clean lines. You will also probably end up with a silver patch on the heel of your hand from dragging it across all those light lines, along with a gray haze - a delicate touch with a kneaded eraser can fix that, or just draw with a col-erase pencil, finish with graphite, and abuse the levels in Photoshop to drop out the color.

Being able to knock out a drawing with precise lines and no underdrawing does take years, but being able to simply create a drawing with precise lines can happen a lot earlier once you've picked up a few One Weird Tricks.

Maybe for some people, but not everyone.

I have developmental dyspraxia, a.k.a. developmental coordination disorder. I'm never going to be good at anything that requires fine motor control. Maybe at best I could get the first few strokes of a drawing to look good, but after that it's going to fall apart. I know this from my experience with seriously trying to improve my handwriting back when I was 24 because I was tired of writing chicken scratch all the time: I can now make the first few words of a paper—maybe if I'm lucky even the whole first line—look fantastic, but after that I just lose any sense of alignment and proportion and everything starts slanting in random directions and changing size all over the place.

It is a medical condition, and there is no cure.

[0] This image on Wikipedia sums up my handwriting pretty well. It's specifically about motor dysgraphia [1], which is part of my dyspraxia. https://en.wikipedia.org/wiki/File:Dysgraphia.jpg

[1] From https://en.wikipedia.org/wiki/Dysgraphia

> Motor dysgraphia is due to deficient fine motor skills, poor dexterity, poor muscle tone, or unspecified motor clumsiness. Letter formation may be acceptable in very short samples of writing, but this requires extreme effort and an unreasonable amount of time to accomplish, and it cannot be sustained for a significant length of time, as it can cause arthritis-like tensing of the hand. Overall, their written work is poor to illegible even if copied by sight from another document, and drawing is difficult. Oral spelling for these individuals is normal, and their finger tapping speed is below normal. This shows that there are problems within the fine motor skills of these individuals. People with developmental coordination disorder may be dysgraphic. Writing is often slanted due to holding a pen or pencil incorrectly

[jdietrich]

There are a number of excellent artists who have cerebral palsy or tetraplegia. If you have limited fine motor control, you can paint or draw in large-format using gross movements. If you shake or twitch, you can work in mosaic, collage or pixel art. If you can't grasp objects, you can use a typewriter to make pointillist drawings.

To be fair, I've recently gotten into typesetting anime fansubs, and I've found it to be highly rewarding.

It doesn't require any fine motor skills, as it's all done in a really janky scripting language called ASS. I can do all kinds of four-dimensional text transforms just by writing code, and I've been able to produce some wonderful-looking effects.

Uh. I'm a professional artist and my handwriting looks about like the bottom half of the sample most of the time, unless I am explicitly focusing on making each letter look pretty.
