As someone who started a nonprofit to speed up pharmaceutical drug development, this quote rings very true:
“The amount of money you need to develop these technologies at the early stages is much less than what you need at the later stages, but obtaining money for the later stages, like clinical trials, is much easier because much of the de-risking has already happened. Since philanthropic money is only needed at the early stages, the answer to that question is a relatively tiny amount of money: 500 millions or even 250 millions over a period of 10 years, which is an order of magnitude of what SENS currently has, which is about 5 million dollars per year. 250-500 millions is still a pitifully small amount of money as compared to the kind that’s spent in medical research generally.”
Disclaimer: The bulk of my recent personal giving ($1k) went to SENS.
