IANAGM so I can’t speak to why they are funding or not funding the specific bets they are/are not funding.
But, speaking abstractly, grantmaking in AI safety is conceptually complicated: Do you take a wide range of bets on unproven theories of change and new grantees, or do you narrowly fund only bets which you have high confidence on? How do you balance between the two?
My intuition is that AI safety puts 1-2 cycles of funding into first-time bets, and quickly moves on to the next set of first-time bets while only continuing to fund orgs and people who used their early money well (and had something to show for it, even negative results). One could argue that funders should be biased towards funding orgs/people for 3 or even 5 cycles before pulling the plug, but this is ultimately a hyperparameter in a quantitative model. It’s not obvious to me that the current settings of such hyperparameters are the wrong ones.
With more funding and increased diversity of funders, I absolutely expect more funding philosophies and models in the ecosystem, increasing the kinds of bets being taken.
I didn’t know what you meant by “elide”, but somehow both definitions work!
