If everything on show at open sauce were those stupid 3D printed dragons I'd agree with you. But the maker movement is massive and interesting and goes very very deep.

You can self-learn as much about engineering as you'd learn at university. Most kids eventually pivot from wanting to be astronauts/influencers to something more realistic.

IMO tinkering is an amazing hobby which will benefit you in whatever direction your career ends up going in.
