"So here's why I did. It was a personal challenge. I stayed out here in this driveway and I practiced about 5 minutes every day. ... after 8 month it happened ... in two weeks he (the son) did something that took me 8 months to do".

Well, if you were serious about learning a skill you wouldn't just do one 5 minute session per day for eight months.

A more appropriate training regime would be way more intensive than one 5 minute session per day. Are we to believe he limited his son to one 5 minute session a day?

Do children really learn languages quicker than adults? By age 3, children will probably have words for almost everything. Babies might even say mama and dada by 6 months of age.

Children have several language learning advantages over adults: complete immersion; it is imperative they learn; effectively unlimited time; no responsibilities.

But, it takes them years to learn their native language to basic competency.

Compare: an English speaker can learn Afrikaans, Danish, Dutch, French, Italian, Norwegian, Portuguese, Romanian, Spanish, or Swedish to General Professional Proficiency in Speaking and Reading in 600 hours carried out over 24 weeks (25hrs per week). Cantonese, Mandarin, Japanese, Korean, or Arabic will take 2200 hours over 88 weeks (25hrs per week).[1]

Is it easier for a child? Yeah probably, they don't even have to look after themselves.

If I could live as a child in a foreign language house in a foreign language city, with only two tasks: learn to speak and read the language to basic competency, and learn to ride a backwards bicycle, I'm firmly of the believe I could out pace the 95th percentile of children at both tasks.

As an aside, he says his son is the closest person to him genetically, but aren't his parents both equally as close to him genetically as his son?

And any siblings.

So it only took him about an hour, over three days, to get it worked out well enough to not immediately fall off, and an hour and a half over four days to get to 50 meters.

There's a comment in on the YT video from Destin saying "the RC helicopter pilot was able to learn it in about an hour but I don't think his brain is normal" - good point, the RC helicopter pilot has more experience understanding reversed input while the helicopter is flying toward him, also he had the opportunity to watch Mike learn first.

I reckon the learning process could be sped up even more by taking the pedals of, turning it in to a balance bike, learning how to ride it down slight inclines, get that sorted then putting the pedals back on.
