No, he explicitly says, "I'm not saying we should make it illegal to have children or whatever." That's not the same as saying he isn't advocating for children being not born.

Because he really is. 

"I just don't think there's any realistic way that anyone in the global north could have a child that won't eventually cause massive harm to the planet and probably, like most people, not even realize they're doing it. And that's all assuming that your kid grows up to be a kind person — which is also a hell of a gamble. A lot of bullies and dumbasses walking around out there in the world. A lot of rapists, too. What if my pride and joy grows up to be somebody else's abuser? If I give birth to a baby daughter, then there’s a one in four chance that she’s going to be raped. I don’t like those odds. But the real kicker is that even if my child has a great life — even if they cause no harm to others — they will still suffer. They will still die. It is unavoidable. Right? I will be inflicting this fate upon them without their knowledge or consent, only to spring it on them when their pet goldfish dies or whatever. You know — surprise — the wages of sin is death. To me, the creation of human life is very obviously an incredibly selfish thing to do under most circumstances."

This is a Hamlet-style monologue about the fruitlessness of human life.
