IMO the lessons aren't really patronizing.

I'd TL;DR them down to "Whatever your bright idea is probably isn't as original as you think. If you think nobody else has thought of it you probably haven't looked very hard, or if you're very lucky the numerous other people who thought of it at the same time as you or before you never pursued it".

We all live in the same world (now more than ever), we're all influenced by the same things and IMO ideas are more tied to a time and the zeitgeist than they are to any person, every personal and historical "bright idea" I've ever encountered backs this up in my experience.

This is why ideas are a "dime a dozen" and execution is everything.
