For me, the main thing I love about Tailwind is that I don't have to create ad-hoc class names. No more BEM.

That's only problem in the USA. Other western democracies are able to have snap elections done in two months.

> Look at the typical React dev. They have zero leverage and can be replaced by vibe coding kiddies straight out of school or sourced from literally any company on earth.

Good luck maintaining such code. As we know from constant whining here on HN ("Hooks are too complicated..." "I don't understand useEffect"), React's model feels slightly more complex than other frameworks' models.

I can even argue that the more popular React is, the more React developers are needed.

I'm talking about how a single product is produced, not about its evolution through centuries. Anyway, the point wasn't to compare specific details, it's just an analogy.

I'm not arguing against the core arguments of the article (I agree with most of the points), but on the other hand, software development is (at least currently) an essentially iterative process - one that differs greatly from other production processes (e.g. buildings, cars). We all know how difficult it is to estimate how much development time something takes. Planning is hard and outcomes have therefore greater variability.

My guess is Gatsby wasn't chosen because it was a bad framework that is practically deprecated [1]

If you're not into web development, Hacker News discussions about React are really bad way to gain unbiased perspective - it's been really popular here for last few years to just hate React (usually they know nothing, e.g. anyone who claims hooks compose worse than class components). But there's a reason why React is still used the most (large ecosystem, fast development and backwards compatibility). Of course, it's easy for inexperienced developer to produce slow and buggy apps (maybe slightly easier than in other frameworks, but that's practically unquantifiable), to include unnecessary or even badly written dependencies, etc. - but it's not the tool's fault when it's being used incorrectly.

Gatsby was sunset because it was a bad framework build on bad decisions [1]. I tried to use it when it was new, and it was immediately obvious that "GraphQL for everything" leads to horrible DX.

What's there to contrast? It's basically the same experience as I had.

Just before Covid when everything was cancelled I booked some tickets through Kiwi and it was the worst decision - I spent year (!) getting my money back. I'm not saying Ryanair is a good company, but for their flight (i.e. one of those which I booked through Kiwi) they reimbursed me immediately. The second flight was EasyJet and they said they already sent the refund to Kiwi, while Kiwi said they got nothing. In the end it was Kiwi who sent me the rest, and in my view they truly are parasites (they also got a Covid loan from the Czech government). Maybe in the days of Skypicker when their search engine was good they provided some value, but nowadays I advise everyone to avoid them.

Raising kids is expensive, and today young people can't afford their own home - how can they have children? Sure, other things may also be affecting this, but IMO raising inequality correlates very well with lower birth rates (at national level); anecdotally, all my friends with high income are having at least two kids.

I'm assuming John Ousterhout's book A Philosophy of Software Design [1], which I would recommend reading before reading about design patterns, because it's more fundamental.

I would love to see that pull request, and how readable and maintainable the code is. And do you understand the code yourself, since you've never done this before?

Exactly what I experience. I don't need AI to generate complex algorithm, I need e.g. a lot of code for a UI library that is clean and maintainable - but it's can't ever generate such code and it can't be prompted, because training data has much less excellent code than good and ok code. Therefore I can't use AI for high-level design task, ony low-level code, which I then have to check and clean line by line, and that isn't an enjoyable work.

I don't need LLMs, I need some kind mind reading device :D
