The “Should we get rid of the GRE?” conversation and the “Should we pay undergrad RAs $15/hour?” conversation have three things in common that I think are really unfortunate — 🧵
Some musings about graduate admissions, standardized testing, etc while I wait for my coffee.... these are things that seem obvious? but are maybe not obvious?

More from Economy
Interesting thread, but I don't think ecosocialists or degrowthers are arguing that if German socialists had come to power the world would be green by now. Socialism is not automatically green. Eco-socialism is what it says - a green version of socialism - to be tested /1
The historical counterfactual also in not totally convincing. So let's assume Germany and Europe went socialist. The world economy would have evolved exactly the same way it did? 🤔 I doubt it, this is too deterministic. Examples: /2
We do not know if the transition from coal to oil would have taken place when it took place, the way it did. From Timothy Mitchell we know that oil was a fix for capitalism to bypass the labour strikes of coal workers. One would think that socialists would treat workers better /3
We also do not know if socialist governments would strong arm the Middle East the way capitalists did, starting wars to secure cheap oil, and setting up puppet governments. One would want to think that Rosa Luxembourg would not go down that path..../4
We also do not know if they would have continued colonial unequal exchange, extracting raw materials as cheap as possible from the rest of the world. Without cheap oil and cheap materials, it is anyone's guess if GDP and CO2 would be where it is now. /5
You get the impression from the eco-socialists and degrowthers that humanity wouldn\u2019t face the threat of climate change or biodiversity loss if it weren\u2019t for capitalism (or rather, if it weren\u2019t for capitalist modernity).

But I see no evidence to suggest this is the case.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.
Legacy site *downloads* ~630 KB CSS per theme and writing direction.
6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices
https://t.co/qyl4Bt1i5x
PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.
735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.
The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
