Why so?

Life needs energy, we can harness energy better to produce engineered food and desalt water.

I'm not referring to quality of life, but "living" in the broader sense including the enabling infrastructure and resource dependencies as they stand today.

ok but technological evolution follow the same curve. We would not be able to sustain current population with 1900 technologies. It's very strange to completely discard technology evolution in this equation.

if you harness too much of it, waste heat boils you off anyway.
