Is this meme the single greatest reason why the developed world has so few successful moonshots? Imagine if Elon Musk took this approach with Tesla/SpaceX/Boring/Neuralink, or Steve Jobs took it with the iPhone.
The best class of startups is where the key risk is not "is there a market?" but "can this be technologically pulled off right now?" For example, if in 2002 you had asked a random smart person "suppose I build a reusable rocket at 1/100th the cost of a normal rocket; do you think there's a market for this?" The answer would be "of course, but could you really build that??"
(With all due respect to the founder of MeetButter; some companies naturally fit the quick MVP approach, but they tend to not be technological moonshots).
