As an aside: I tried using claude to write GTK4 applications in december 2025/january 2026 and it was awful at it, barely even helpful. Then in September it's writing great gtk4 apps with barely any prompting.

The capability ceiling of models in general has risen massively in not even one year. Back in 2025, I also found them to generally be a net-negative expense of time and effort. I wouldn't universally make the same claim today.
