I as well. Though not the term, the idea is very old. In Ecclesiastes 4, Qohelet says something like The dead are better off than the living, and better still are those who were never born.

I will say that the question of whether the living should commit suicide is rather different than whether new lives should be brought into the world. Sunk costs and all that.

We will all be dead soon enough. Not sure there's much point in speeding things up.
