My memory isn't the best, so when I kept hearing that Apple was happy to engage in re-designing challenging APIs in areas it had previously poured cold water on, I had more than a moment of self-doubt. Had I missed something fundamental?

I've been hearing confusing reports of Apple's openness to collaboration on challenging APIs so often that either my priors are invalid, or something else is at work. To find out, I needed data.

Want to build faster websites? Here's how:
- Learn how browsers parse, layout & paint
- Treat JS as a tool, not the foundation(!)
- Favor static HTML or server side rendering at all times
- Use Core Web Vitals alongside other metrics to learn shortfalls, improve and iterate
Then keep doing that.

As a child, my favorite TV show was about a guy whose best friend is the AI in his self-driving bulletproof car. I thought that was the coolest thing.
But as reality slowly catches up to that fiction, I can think of nothing sadder.

As for your juniors, the correct response is that building appreciation for the platform below you and building for it more effectively are the path to senior and beyond, not shipping more features or writing more code. Seniority requires taste, and taste requires understanding.
