Disagree with 2nd statement. Tailwind is awesome for frontends, the way forward is to learn to compose. As long as you use bem style convention, with simple "flat" selectors, you can use both sass and tailwind and write less css (instead of no css, which I find extreme and impractical).

However that also means its perfectly ok to have one’s own system (cf. twitch, github...). Why not use a standard though? Tailwind saves us so much time coming up with a solid consistét utility set.

And then combine it with Sass
