I wonder if being around so many people burns us out. Having a kid ensures there will be someone always at home, so after a day of swimming through strangers you don't get solitude at home.
While full automation has a low probability in our lives, the chances are much higher for the next generation. So in my potential child's life, they very likely wont be able to remain employed.
How do we currently treat people who aren't working right now? Terribly. This means (IMO) it's best for the child to not exist.
Perhaps you might think, "I'm smart and I will raise a smart healthy child, and that won't happen to them." Welp even if the stars align and nothing goes wrong, what kind of a future is that to leave them? Endlessly competing for the last few living wage jobs in existence? That doesn't sound like a free life to me.
Consent of the unborn is not given while creating life. Now that we have an option in weather or not we create life, we should exercise it with responsibility.
