...so, you haven't used Android in over a decade?
That was… *checks CV*… I left in April 2015.
I think RAM is like roads: usage expands to fill available infrastructure/storage.
That an iPhone today has as much RAM as the still-functioning Mid-2013 MacBook Air sitting in a drawer behind me is surprising when compared to the 250-fold growth from my Commodore 64 to my (default) Performa 5200… but it doesn't seem to have actually harmed anything I care about.
Swimming in badly written SPAs and cordova/whatever hybrid apps is seriously helped by eg 12GB of RAM on a mobile :)
