I think you make a lot of good points even though I ended up disagreeing with your conclusion. For now I'll reply to just one argument, since no one will probably even read this one:
"Seeing someone willingly make personal sacrifices for the sake of morality encourages others to act ethically, too."
I think that striving for veganism actually discourages most people from acting ethically about animals i.e. offsetting their footprint with donations, because it's adding a hurdle in the path to helping animals.
It's like demanding people do handstands before entering the gym.
It also reminds me of oil companies pressuring people to do their part by turning off the lights when not using them and shortening showers. It seems like a trivial distraction from the systematic change, and the funding and broad public support, that is really needed.
I think Humantix cofounder Josh Ross is dope.
In this podcast with Peter Singer he says he got into the digital ticketing space with the purpose of developing software that can be scaled up into a tremendous source of charity.
In that podcast he also was incredibly honest that he is also motivated by a fear of Hell
To be honest I can relate to that but unlike him I haven't donated over $10,000,000 yet. That's according to Humantix's site today, which says it donates virtually all its profits, to nonprofits including Peter Singer's The Life You Can Save.
P.S. In various interviews like this one he says his long-term goal is to create more tech innovations that can generate more for charity and disrupt more industries than just ticketing. So maybe get in touch if you want to help him out with that.
P.S. If it's not too personal, I'm just curious how is your first video (on AI 2027) so incredibly polished? Did you work with a more experienced videography team?
