Given that AWS and Azure have both made commitments to have their data centers be carbon neutral, and given that electricity and heat production make up ~25% of GHG pollution, I find these sorts of power-usage-analysis-for-the-sake-of-the-environment to be a bit disingenuous. Especially since GHG pollution from power generation is forecasted to shrink as more power is generated by alternative means. I am fine with improving python performance, but let's not fool ourselves into thinking that it is going to have any meaningful impact on the environment.

Bingo. I lived through the Freon ozone panic that lasted for 20 years even after the key reaction rate was remeasured and found to be 75-100 times slower than that used in the research that started the panic. The models never recovered, but the panic persisted until it magically disappeared in 1994. There are still ozone holes over the Antarctic, last time I looked they were explained as due to an influx of cold air.
If you want to deal with GHG, push nuclear power.
