What are examples of "Modern UI"?? I think of Mac OS X, my Garmin watch or the Leica M10 UI. They are modern but I do think their UI would still be good in 40 years
I used macOS and I'm not sure of others. I'm not totally against animations on Modern UI. But I think it is used heavily in certain places like twitter for example. The profile parallax transition and other animations is kinda laggy when I'm on the low-end processing machines. Also Airbnb's new design and Apple's product pages are heavy if I'm on a slow network. Animation/transition are mostly used to cover the slow network latency. Also most people think that it is fancy to use animations rather than solving a problem. I think design should be consistent across devices and networks, showing a different design for users on a slow internet connection is kinda ugly.
