I feel there are lots of parallels in e.g. Maths education in the more generalised form:
In education, skills that allow you to utilise technology are prioritised and these are often directly opposed to skills needed for mastery.
I'd even go further and say that training wheels optimizing for utility instead of mastery teaches the secondary skill first, so the child can pedal and add power without needing to learn to balance the bike. So, when the training wheels come off, they've got effectively nothing.
And this certainly applies to every other sort of teaching, where learning the mastery-related skills can seem so irrelevant at first.
I'm not sure this is actually true at all. Kids can go pretty fast on a balance bike. Probably as fast as on a bike with training wheels. And for kids that small, gears are mostly useless anyway.
I was flabbergasted.
