It clearly hasn't though, as demonstrated by this very OP ;)
Everything people are complaining about here, in addition to the problem being addressed by Concurrency Mode, are things that writers of native apps don't have to fight with:
- Lack of concurrency
- Complex, layered build systems
- Several layers of syntax transformation as an industry baseline
- Lack of a consistent story for modules
- Overall jank-proneness
- Platform bloat like that in Electron
But then why re-solve all these problems if you can just build a native app? Because native platforms over the decades have repeatedly tried and failed to a) be truly cross-platform and b) have truly flexible, well-documented layout systems. The web gives us those. We just have to go back in and add the things it lacks.
When all of these problems have been solved and a new framework is still coming out every week, then we can talk about frivolous effort being expended. Until then these are real, worthwhile problems being worked on.
That's where I disagree. I think the web was fundamentally unsuited to the "application" use-case and has been making its way in that direction for 5-10 years now. I think once we reach that destination, the churn will drop off dramatically. The platform will become enough, for the most part, and we may shrug off the need for comprehensive "frameworks" altogether in favor of simple libraries, like most other language ecosystems.
