Like where do you think we are? https://en.wikipedia.org/wiki/Kardashev_scale
Seems to me like you are expecting too much. Worst part is, if that kind of thinking - do not exploit nature wins out - we might not even get there. Exploitation is key for scientific advancement in capitalism.
In capitalism? You mean, compared to the sustainable and non-exploitive nature of communism, for example?
The universe doesn’t grade on a curve.

What a weird objection. It’s our science that tells us we need to radically reform how we consume resources. I’m not worried we’re going to waste all our resources in scientific endeavors, I’m concerned that we’re destroying the environment on which we depend for frivolous short term gains.
