I actually wouldn’t be surprised if this were the case – the whole schtick of a lot of these people is “worrying about increasing the number of future possibly-existing humans, even at the cost of the suffering of actually-existing humans”, so being anti-abortion honestly seems not too far out of their wheelhouse?

Same energy as those score-maximising Tetris AIs that taught themselves to stack blocks to the kill line and pause.

Like I think in the EAverse you can just kinda go “well this makes people have less kids which means less QALYs therefore we all know it’s obviously bad and I don’t really need to justify it.” (with bonus internet contrarian points if you are justifying some terrible thing using your abstract math, because that means you’re Highly Decoupled and Very Smart.) See the quote elsewhere in this thread about the guy defending child marriage for similar reasons.

Ughhh yeah that sounds about right.
