I'm not really waiting for him to become vegan. I'm waiting for him to become rational - veganism follows from that. He doesn't have to promote it, he just has to live it.

I'm doing plenty of positive changes while waiting and pointing out his irrational argumentation over energy.

One is replying here with a unique opinion.

The other is applying my own engineering skills, tied very tightly to logistics (NP-hard optimization).

Bill Gates is a huge driver for startups and people reinventing the food industry. But his posts on energy never include the biggest luxury of all, the mightiest polluter, the strongest destroyer, the most prolific murderer - the animal agriculture industry. Without it + great logistics, the greenhouse gases emissions he's so eager to reduce would reduce immensely.

When animal agriculture footprint becomes smaller than all traffic combined, when it becomes smaller than all of the heating - then I'll concentrate on other things.

Anyone profiling a program would optimize the big percentages, not the small ones. Having a couple of thousand people watching my region centered vegan cooking videos is nothing.
