I disagree. The pie-in-the-sky academia dreams are not risk, they are safety. ITER and CERN and similar do fascinating research, and I don't mean to throw any shade their way, but they do not represent risk. There's not any possibility of failure. Things could go completely sideways and papers would keep getting written and no bureaucrat would lose their neck.
On the other hand, most startups have the ability to be total failures. If your social network, or your rocket company, or your new type of airplane collapses, it is a total loss. That is risk.
