That said, I got into web dev when I was a pretty young kid, about 9 years old, and I would have fun hacking together different websites. Eventually I noticed the “edit” button on top of the browser and learned you could mess with other people’s sites as well. I had lots of fun breaking stuff.
Computers are so cheap now, I think it’s relatively easy for most families to have a computer that can be programmed. For that matter, the Raspberry Pi is cheap and has hundreds of resources available to play with, many of which are kid friendly.
