I Row-Boat by Cory Doctorow. I heard of it via The View From Hell, the blog of a “non-practicing suicide”. The host of that blog, who goes by the name “Curator” has also been assisting Jim the anti-natalist against Hopefully Anonymous in the most extreme pro-natalist post I’ve come across. That post in turn is probably inspired by Eliezer Yudkowkskie’s magnum opus sci-fi fable that sums up a great deal of what he’s  written at Overcoming Bias and how it relates to his life’s work.
