Expert "How To" Videos

I've been watching youtube videos about cornering a mountain bike for a couple of weeks. I think the general category of expert "how to" videos is quite interesting and they show why the sci-fi nonsense sales pitch on "AI" is so dumb.

Many of the MTB cornering videos follow a "break down" approach, that is, they present cornering as a multi-phase, multi-step sequence. Step 1--look into the turn, step 2, lean the bike, step 3, position your body, etc... The concept is through repetition of the steps, a rider will become proficient at cornering.

That's not what happens at all though. What really happens is the riders brain and nervous system eventually encompass the bike so they can "feel" the tires on the ground and feel the orientation of their mass distribution on the bike. Once a person is an expert, they can ex post facto explain what their body is doing when they're cornering, or doing a hand stand, or whatever. To the novice, the word salad really isn't helpful. If anything it's kind of counterproductive.

I realize I don't have good feel for the bike's wheels. It's frustrating for me as a long time cyclist to throw away so much precious speed in a hundred corners by even feathering the brakes when I should be able to just rip through the corners. That said, I really do not want to crash and break the bike or my bones.

Anyway, it's obvious I will not learn anything from the videos; in fact there's really an obvious course toward improvement. Go to a free form loose ground area, like a big gravel parking lot, ideally with a slope, setup some "corners" by drawing them with a stick, then turn over and over and over and maybe take a video. The advantage of a parking lot is it's easier to repeat--more tries per unit time, plus a missed corner = rolling over a line instead of crashing into a tree.

The thing I'm really trying to do here is extend my nervous system to the contact patch of the tires and the ground. Currently, there's a big void there. Learning to ice skate or rollerblade is actually a very similar process. Prior to developing "feel" people are generally all "hands, head, and feet". If you watch a novice on rollerblades, they flail their arms around as their head and feet rotate around their center-of mass. They're generally oblivious to their center of mass, which is quite interesting.

Developing feel is a nonverbal process. Really words provide very little useful information for developing these skills. This is the severe limitation of so called "AI" because this concept of "feel" is pervasive in human endeavors.

In fact, it's possible to sort of flip this concept around entirely and see the effect of the dullard verbal mind model on the world. In general people dislike an irregular and even mildly challenging world where even the smallest obstacle is intolerable. They do not want to learn anything, ever. They don't want to condition their body for balance or strength or mobility. They don't even want to pay attention when they do something insipidly simple, like drive a car. It'd be good to understand what they really want. Like what's the goal of the average person when they're doing all the nonsense stuff they do?
