When a spouse says “Not tonight, honey, I have a headache,” this potentially adds to the ranks of the unborn; so shouldn’t that be regarded as pro-choice?

Not only am I pro-choice, I would like to see zero births over the course of the next decade. Perhaps that might buy us enough time, as we think long and hard about what we need to do to sufficiently change how we’re living on this planet. And ten years is not a long time. Horseshoe crabs, for example, have been around for some 400,000,000 years!

Of course I don't know what else his ideas are, but it sounds like doing a bit of a Malthusian and gift money. He tells us he never really worked/connected with people.

He doesn't say.

He claims to have 104 "ideas". For idea number 41 he said someone could "even expand on it and be in the running for a Nobel prize for economics", but he graciously doesn't seem to be interested in it. Nor does he explain what the idea is.
