People who decide to write big web applications that run on the cloud using Python instead of basically any language should be harshly censured.
Another route I've been keenly pursuing is aggressively reducing download sizes in web apps I build: JS, images, HTML, CSS, the lot. No web fonts. I'm exploring Svelte as a means to reduce the JS component too, so client energy consumption due to JS ops is reduced.
These can all seem like trivial micro-optimisations, but "cloud computing" is a bloated monster. Billions of web app interactions per day and a few kB here and there soon add up.
