Another option for those with FAANG (or other) money: Personally fund other people who are already doing research or "deep" work. Perhaps first people you already know, and then strangers on the internet who are asking for funding. These other people doing research or deep work are likely to have the qualities and knowledge to effectively direct the usage of funds in a manner that progresses their work; also see the comment by 'joe_the_user.
(There is currently no shortcut for determining who to fund, as it ultimately comes down to a synthesis of intuition/taste and empiricism. Current funding systems are overly biased toward a form of empiricism, i.e. an implicit assumption that past results signal and legitimate the potential for continued future performance. Deciding on the basis of one's own intuition and taste is one approach to correct for overreliance on externalized empiricism.)
