>> I used ballet because people start young

More than 75% of the British population has access to the Internet[1] today.

Less than 0.5% of the sampled population had participated in ballet at least once in the course of a year, in the most recent survey year I could find[2].

There are less similarities than there are differences in the computing / Internet to ballet comparison. I don't feel it's a useful argument.
