You mean Joe Kraus's advice? That's advice for making money at something before your funding runs out. If burn rate is a factor, you may not be able to survive a contemptuous initial reaction, even if you're right.
I suppose you're right and I only found it general advice because it completely applies to my current state in life. Lots of people make that mistake: "this totally applies to me, it must be good advice generally"
After the first $10B, once I start working on a space elevator and robotic asteroid mining, I expect the luxury of a contemptuous initial reaction.
