TFA isn't coherent.

> Questions like “Is this language better than that one?” or “Is this framework more performant than the other?” keep coming up. But the truth is: users don’t care about any of that. They won’t notice those extra 10 milliseconds you saved, nor will their experience magically improve just because you’re using the latest JavaScript framework.

Users care about performance. The per user action latency is >10 ms (unless your in bootstrap phase).

> What truly makes a difference for users is your attention to the product and their needs.

False dichotomy.

> Every programming language shines in specific contexts. Every framework is born to solve certain problems. But none of these technical decisions, in isolation, will define the success of your product from a user’s perspective.

Yes so evaluate your product's context, choose your tools, frameworks, and languages accordingly.
