What about technological singularity, alternate power sources, starlink like projects, energy efficient appliances, etc?

Also, China/India are in survival/growth mode, so "sustainability" is least of their concerns right now :( and btw resource consumption per person is higher in first-world countries, https://www.scientificamerican.com/article/american-consumpt... . This is a mindset issue and needs to addressed as well.

P.S. I am hopeful!
