That’s a really good point about preparing for industry. So many people don’t get much experience starting from a blank slate.
I think for me, the question is how to make it a more obvious gateway. As a child we had things like the spartan C64 or logo. There are some modern equivalents but most are simple. Hard to inspire kids with that compared to what they see (vs an 80s kid). Perhaps on online repl (like shadertoy) plus a demo 101 lib with pre baked effect routines and simple graphics primitives?
