If they really like building stuff like this they can get a career that does it, like Embedded Engineer or Firmware Engineer type roles. And if it's just a hobby that's great too.

I'm not sure about the media part, is it because of Youtubers? If so that sounds like wanting to become the modern version of a movie star. In that situation maybe encourage them to do a multimedia class at school and see if they like it.
