The current grant opportunities for starting a new independent research career in academia have not only become increasingly unavailable to young scientists and engineers, but are also disastrously risk-averse. At the NIH, the proportion of all grant funds awarded to scientists under the age of 36 fell from 5.6% in 1980 to 1.5% in 2017. One might ask the rhetorical question: How successful would Silicon Valley be if nearly 99% of all investments were awarded to scientists and engineers age 36 years or older, along with a strong bias toward funding only safe, nonrisky projects? Similarly, at the U.S. Department of Energy and its National Laboratories, high-risk, high-reward research and development has been severely limited by extreme volatility in research funding and by very limited discretionary funding at the laboratory level.
