Around 2010 I met a friend at a bar in San Francisco and within 10 minutes we were approached by someone with a chocolate bar startup. It may have been vaguely associated with developers or maybe I'm misremembering. We got a free sample and I explained I didn't live in the US and I also wasn't an investor. They left and moved on to the next group of people at the bar.
This has always stuck to me as an example of the pinnacle of collective investment delusion that seems to exist in certain circles. They idea that you can shape the world to your product instead of improving the world with your product. You just have to try hard enough.
