Humanity can have just 2 modes of operation (3th one is fake path). 1) is to consume less and less, so we end up like living in tents in dark with population 10B and more.. 2) Smart-manage population growth and cut bullshit jobs, so we end up with 200M-300M people living good live. The choise is yours. I personally would go with (2) option, but its just me. Before anyone hit the downvote button, think about it in math. You only have limited amount of resources and energy. How you distribute it, is up to you.
