The ratio might not be 1:100. It might not even be tilted towards the risk takers. Also some if not most of the examples you mentioned are based research done in universities and defence agencies. That research is typically a much riskier endeavor. That’s why the private sector doesn’t even attempt it and only shows up to productize or build upon that research once the risk for not turning profit is minimized.
