I used to feel similar about riding a motorcycle. Of course it's not the same as it's a machine, not a living animal your are communicating with. But so much it feels like it becomes an extension of your body and you just move by pure thought. Similar to using a game controller I guess but more of a whole body experience.

good observation, motorcycles are definitely the next closest thing as far as complete machine extensions of the body go vs. say, surfing or snowboarding where the body is unmediated by the engine or gyroscopic feedback in its relationship to gravity. the difference between an animal and an instrument is in the expression of intent that is parsed by another being. the sensors interpreted by a computer are a feedback…

What do you mean by mediated by the engine? In snowboarding the board really is an engine. You can define how much friction you give to the slope or your angle to it and therefore throttle. You also engage the board in a carve and get energy out of the carve in transition and this can be controlled by the length of the carve or how you shift your weight or engage your legs. Not to mention the route you decide to take on the mountain and the effect of that topology and snow conditions. This is true for skis as well.

This is an excellent observation. Dressage (for example) is a set of evolutionary constraints about controlling a 600kg similarly trained million dollar animal through tiny movements (mostly in your thighs and buttocks) in order to win prestigious prizes including Olympic medals. The horses react with puzzlement if you are not trained to a similar level - if you are a junior rider, expert horses are incompatible.

How does an ‘easy’ horse react to these movements? Not at all? Is this what they meant in westerns/literature by “a good horse?”

Not at all is fairly close. Think "beginner friendly" (phone?) vs "expert friendly" (nix?) interactions.

"A good horse" is actually one that matches your level, or is only slightly above, whatever that may currently be.

Note that Teitelman eventually gave up on getting machines to DWIM, and scratched that itch by doing dog agility instead.

(the most indirect control I've seen was someone from the local extension program, mounted on horseback, whistling to his dogs in order to instruct them to herd a flock of geese in slaloms/eights around a set of traffic cones. Roping horses still need to be doing their jobs even after their rider has left the saddle and is on foot to tie/doctor the roped critter.)

Reminds me of when people used to get magnet implants in their fingers so they could sense electric fields.

People are still doing this and although results may vary significantly from person to person, there is actually utility to it. One friend of mine was saved from electric shock during his work on multiple occasions, thanks to his extra sense. Bioproofed neodymium implants can even be sourced from shady Chinese vendors at a very low price, indicating a certain level of demand. The only hurdle is finding someone willin…

I don't think that present resolution would be good enough for me ;) - I wish an option with small matrix of tiniest, more sensitive magnets, maybe of varying (resonance) sizes ?

As a touch sense extension it seems intuitive to adapt - but feeling it more like a sound or colors, less as vibration then.. ?

What about inducted solution - like a matrix of nanocoils calibrated to/messing with nearby neurons electrical levels to provide super precise feedback - or to feel it maybe like different keys being focused to press by mm movements ? ( reverse keyboard ?? )

There are certain blocks that are not caught by the filter.

What if alien planets filter their population like this too? Jokers and vague ideaa get "berried" because people downvote anything they don't understand.

What if alien planets filtered their population by coherence, and any effort to be cohesive during communication?

They'd probably have a great time...

Did HN start allowing emojis or did that one slip through the cracks because it pre-dates the inclusion of Japanese emojis?

I can't believe this place bans cleverness and Unicode. Oh wait this is a startup farm

What cleverness of yours has been banned?

Surely you're talking about something besides randomly putting redundant pictures in-line with your posts?
