Do you think most people have 128GB laptop? It’s more likely to be 8 or 16 GB. The OS os likely taking 4 or more, the browser two or more. And if you add any office applications, that’s another few GB gone. Then how many Electron monstrosities you think the user can add on top of that?
Some PM: users are locked in to our ecosystem; they can't load other apps after ours! /s
But for real, the average number of apps people downloading get fewer year over year. When the most popular/essential apps take up more RAM, this effect will only exacerbate. RAM prices have also doubled over the last 3 months and I expect this to hold true for a couple more years.
