Well there’s setting the default search engine. That’s not part of the rendering engine, but remember when IE6 was so much better than Netscape? Or vice-versa?

Well there’s setting the default search engine. That’s not part of the rendering engine, but remember when IE6 was so much better than Netscape? Or vice-versa? If content is way better from one part of the internet, then users will select that corner for search too. WebGPU is key. Apple has been dragging their feet here while their AR / ML teams catch up to the rest of the industry. 8thwall (https://www.8thwall.com/projects https://www.8thwall.com/projects) has some pretty good demos of completely cross-platform AR/VR stuff. All this gets a ton better if iOS somehow supports WebGPU. And then there is user fingerprinting and ads stuff. A ton of fingerprints today are from CSS quirks and the like. Renderers can favor or disfavor these things.
