If we're being really honest, I switch to the next thing because it's fun. The more official reason to move to the next thing is because browsers are a moving target. Browsers are constantly releasing new capabilities. And the overall population of users is always moving onto newer versions of those browsers; even if that migration lags a bit, it happens. When we can use those newer browser features, we can provide better services to users. Vite is exciting because it's built on top of the native ES6 features that are now ubiquitously supported by most browsers. It's such a smooth ride compared to older tools. The dev experience is great, and the end-user bundles are light. I've been very impressed with it. I sympathize with your sentiment when it comes to the back-end. I want stable tools there. But until the front-end platform (browsers) is similarly stable, some churn will be welcome to support emerging possibilities.
