On 1 I think you are making a few common assumptions & the world may actually be more bottlenecked on broadly implementing existing ideas, thus we need higher average intelligence around the world for that implementation.
And a more general point, a lot of genes associated with higher intelligence are also associated with introversion/anti-socialness & with various mental abnormalities like OCD & others. By optimizing purely for IQ in genes you may be creating less collaborative & less happy individuals.
It will likely be simpler to find one person donating a large amount to swap with, but if you really don’t find anyone else then I plan to donate another $751 towards the 2026 $1000 above the line US standard tax deduction. I already donated $249 to Screwworm Free Future.
In addition to Screwworm Free Future I plan donations to:
Lead Exposure Elimination Project (LEEP)
New Incentives
GiveWell All Grants
