> My friend Frank Keil has a terrific new book out (buy it here), in which, among many other things, he mourns the loss of tinkering. Children and teenagers used to take things apart and put them back together again—toasters, bicycles, and especially cars. Keil argues that the decline of tinkering has had profound consequences for children and adolescents’ understanding of the world.

It is somewhat sad that things have gradually become more un-tinkerable. What used to be a bunch of large components over a large circuit board, or maybe even a mechanical system is now a tiny chip with literally no way to tell anything about it when you disassemble it.

On the other hand, there's far, far more resources for dedicated tinkering these days. $5 microcontrollers and electronics kits 20 years ago? Not a thing. Internet guides you can follow to master it all? Good luck with books that are too hard for you to start reading without a mentor or a school. Learning tinkering has never been easier, but people's motivation for it has never been lower either.
