Not at all. This idea that kids just spontaneously form ideas from a vacuum is obviously false. Inspiration comes from all sorts of guidance. I would have loved to know more techniques for building things when I was a kid and was stuck in the rut of similar ideas for a long time. I craved books that showed how to build things. I also created my own stuff but instruction material was gold. It took you to more exciting things than you could think of yourself.
My kids are way more creative than I at same age... because they watch speed builds on Youtube compared to me in a Vacuum in the 90's.
I absolutely agree that inspiration comes for all sort of things, not only those videos.
I applaud this app, I hope it evolves to offer more value to older kids.
