> But the problem is that while kids like it a lot, it doesn't translate to engineering careers.

I think there has always been that though. When having a guitar was cool and people thought they'd be famous doing it. Of course 0.00001% actually managed it, but some craft out a career in music or related areas such as being studio engineers etc. (I did)

And for some it shows that it is possible, that people like them can be enabled and make their own stuff.

It might be that they're are organisations needed to bridge this new gap and get people into more formal engineering, but they'll also hopefully realise that people like them might work one day at top tier engineering companies.
