Hence arguably “impactful ideas” is a misnomer here, because it’s rarely the ideas themselves that are impactful (and you are rarely the first to have them), but what you make based on them.
Idk I’d disagree - see the part about “when someone repeats my idea to someone else with referencing me, I’ve won”. There is indeed a lot of work involved, but the author is trying to create memetic value here, not some software or particular product. Imo.
