It occurs to me that there are some very clear parallels between "energy efficiency comparisons of programming languages" and ""EV proponents".

People are constantly talking about how EVs will be so much more energy-efficient, rather than questioning whether maybe we shouldn't have so much private car usage in the first place.

Likewise, people talk about the efficiency of different programming languages, rather than questioning whether maybe 80% of what we do with them (particularly advertising/analytics-related) maybe shouldn't be done in the first place.
