> Stack: Next.js, React, TailwindCSS, shadcn/ui, four languages (EN/DE/FR/JA). The AI picked most of this when I said "modern and clean."

I’m not an AI hater but I do see this as evidence of LLMs being susceptible to chasing trends as much as people.

Next.js with server rendered React is not a stack that an experienced web developer would have recommended for a “clean” solution to a collection of financial calculators. It’s the answer you’d get if you asked for the stack that’s trending the most lately.

Could be, but that stack happens to also solve for a lot of problems totally unexperienced people will struggle with (such as, to not look too far, CORS issues). Good reco for a non-tech person to build a frontend. And besides, who cares which stack is used as long as its used. Its not like this will ever be maintained. If anything, if a need for a new feature emerges 5 months down the road the whole thing can be re-done from scratch in one sitting without writing a single line of code.

TBH, that's pretty much the stack I'd pick if I were building anything new by hand. If you look at the site, there's a lot going on and Next + React + Tailwind does not seem so crazy.

These are all quite reliable well-understood components, and far from "chasing trends" IMO.

Next.js is 9 years, React 12 years old.

vibe coding so far has really homogenized the tech stacks by the self promoters. Vercel is printing money off this phenomenon that's a self fulfilling snowball. But stack diversity is good, not everything needs to be js/ts
