> We didn't suddenly become better at building internal combustion engines because people grew up with cars. Are you sure? What about people growing up with cars, curious about what goes on under the hood from childhood, with references available on how they work, that they can connect to what they've seen themselves?

It's not obvious that stone age toys are the best preparation for contributing to the next step of the ladder.
