I’m trying to take the article seriously on my own terms, but it seems to me to fall short even then. It mentions that people suffer, and that non-existence may be preferable to suffering. Even insofar as that’s true, don’t people also experience happiness and joy, and isn’t that preferable to non-existence? Why ignore one side of the equation. Surely it’s the net balance that matters?

In polling, most people around the world rate themselves as “happy” or “very happy.” https://www.bbc.com/news/world-30629478. In Africa, a poor continent where many people experience suffering, 83% of people rate themselves as happy or very happy. The simplest things in life, including having children and forming families, makes people happy, regardless of the suffering that might also be a part of their life.
