> If I gave $500 to kids cancer research every year for 5 years, and then I don't give this year, do I have blood on my hands every time a kid dies of cancer from now on? And if you didn't ever donate, you don't?

> How does this work?

Okay, since the topic at hand is steelmanning, that is, replying to the strongest possible argument, let's practice that.

I invite you to watch this video, which is a short lecture that indeed exposes the strongest argument for this exact proposition.

I think the video is the best short exposition but you could try reading the paper the video is about

Or reading about the paper
