I think it’s a little more nuanced than the broad takes make it seem.

One of the biggest performance issues I witness is that everyone assumes a super fast, always on WiFi/5G connection. Very little is cached locally on device so even if I want to do a very simple search through my email inbox I have to wait on network latency. Sometimes that’s great, often it really isn’t.

Same goes for many SPA web apps. It’s not that my phone can’t process the JS (even though there’s way too much of it), it’s poor caching strategies that mean I’m downloading and processing >1MB of JS way more often than I should be. Even on a super fast connection that delay is noticeable.
