Just watched the video and yes, I completely agree with the guy.
I think the cat is out of the bag and we are most certainly going to end up with around 11B in the near future.

You have managed to strengthen my resolve to never bring another pointless life into this catastrophe in progress. I didn’t think that was possible. :)
