Increasing risk alone does not increase the expected outcome of an enterprise, it reduces it. Risk is one important factor in the equations determining whether or not a business proposition like YCR's funding scheme is attractive, and for this reason the topic needs to be addressed. You are right that people who take more risks are more likely to create something great but the likelihood of a failure increases even more. Increasing risk therefore comes at a high price.
At the level of an individual increased risk does indeed reduce the expected outcome of an endeavor. However, societies where individuals are willing to take higher risks end up reaping the benefits that are only accessible by taking higher risks. One example of such benefits are scientific discoveries.
The current combination of risk-aversion and the focus on publications, tenure and positive results that permeates academia is antithetical to the uncertainty inherent in scientific research.
It seems to me that building new research institutions like YCR with a culture that resembles the one in tech which accepts and encourages risk-taking should be a priority if we are to continue to make progress in science.
