I just want to complement you for this excellent distillation of the problem with this kind of course without descending into backhanded complements.
When I heard about the course, something did strike me as "off" in the sense of needing to be explained. It feels like a shortcut, a whirlwind tour, or worse, a "master class" that leaves out something important. And what it leaves out is the grind, and the tedium, and the meta-understanding that those are aspects of successful work.
After "Borrowing Brilliance: The Six Steps to Business Innovation by Building on the Ideas of Others" I'm not so sure about that.
The idea this book talks about - I think central, but not the only one - is that creativity at least closely related to combinations and transfer between fields.
But he can't communicate all of the skill transfer he is doing in a way that your brain will change to see things the way he does – no one can.
1. I think people frequently underestimate how useful it is to do the "boring" parts of engineering (or any discipline). The unfortunate reality is that a lot of learning (that can be applied generally) comes from failure / mistakes, and you don't really get that if you're taught "this is how you can make this particular cool thing". In other words: I don't think you can learn how to do the stuff Rober does on YouTube by Rober telling you how he does the stuff on YouTube. He is capable of that precisely because he studied engineering in school and worked at NASA etc and experienced failures and setbacks which, though not obviously related to making a glitter bomb or w/e, taught him lessons and skills that are helpful under the surface. This is generally why I'm skeptical of anyone that thinks they can distill down their success in a given field into a single book or video series, when invariably their success is a result of 10+ years of experience, practice, and overcoming obstacles.
2. Creativity is near impossible to teach, which effectively just makes this a 30 day engineering course, in which case see point (1).
Hopefully my skepticism is misplaced though and this is a very worthwhile course for a lot of people!
