For a MVP, it's hard to beat Phoenix Framework channels and Liveview, and if you want to completely decouple the UI from the backend with something like a native app, or separate webapp, it's absurdly easy to just add the resources to a route that goes through the :api pipeline instead of the :browser.
Once you are ready to outgrow a single machine deployment, the BEAM clusters so well in a way that works the same on your dev machine. Also if you want to get really complicated multi-service design, Umbrella apps are leagues better than docker-compose setups that I have had on dev machines that make a 16G Macbook pro instantly put everything into swap.
Half of the reason that I enjoy using GNOME, KDE, and other distros is that I can theme the entire system for a relatively consistent experience. I enjoy having system apps all be the same configurable color theme and even design language with flat themes and material themes becoming popular.
Layouts might be a bit much, but themes are a key part of the user experience.
I think the bigger issue are that devices are trying to handle many things at once, and badly. I stick with projectors (which keep getting more affordable) which just handles video, and an audio system which just handles audio. No smart tv bs, and I just use a fire stick/chromecast/laptop to handle the content.
I'm more than happy with my setup, except that I usually want to wait until after sunset to watch shows or movies. It's probably better for my own free time to not spend a day watching tv anyways.
