We can optimize chances for successful experiments, and I doubt optimization involves having a lot of hands on by tech CEOs or the wives of tech CEOs (Zuckerberg and Bezos wives’ come to mind, but there are many cases). The Gates foundation and others that have had success in various areas are relatively hands off, or “bottom up” in their approach. One can spend money to feel good, or one can spend money to do good. A lot of tech CEO/tech wife CEO philanthropy is the former.
