As our users are global with varying devices not everyone will have the latest hardware though. Again, I agree, if you are lucky enough to have current gen stuff, then these things are less of an issue, but the majority of the world has something that is maybe 5 years old or so. I myself still use a Pixel 2XL for example for my personal phone and only this year upgraded my desktop (of 7 years old!) but I am still running an few years old GPU due to the current GPU shortages.
Looking at recent research papers in 2021 though folk are still resizing to lower resolutions eg:
[2103.09950] Learning to Resize Images for Computer Vision Tasks 1.
But the way in which you do the resizing is important it seems.
