Why not - global economy - will grow with improving productivity & efficiency. Assume we replace all the stupid cows we have now - with super genetically engineered cows - that produces 3 times
milk or meat - that already triple that sector - consumption will also triple as more people to afford to buy milk or meat- do the same for every industry - and you have richer world.
As long as humanbeing continues investing in research, science, technology and trying to be better - the world will continue being a better place for next generation.
Do we have enough resources to triple world economy. The good thing is that most of Asia population is aging so if we can stop prolonging human life for no good reason. We can survive with current growth rates. I have come to realize that high income and quality of life come with a very great cost to environment and social order. Anyway we may be three generations from end of human species
