Yeah, and even native stuff is super bloated now.
I noticed an instance of Brave with all of the features turned off sitting at a new tab page was using 230MB.
I remember doing OK with a version of Firefox that supported xhtml and JavaScript 2 that ran on a machine with 16MB of RAM total.
And the current browsing experience isn't somehow instantaneous on a CPU with 16x the cores running at 10x the clock. The user response time is about the same.
I think that browser itself ran in 4-8MB. Probably with the Flash plugin loaded too.
FWIW that old machine would take about 15 minutes to encode a 3 minute mp3 file and my current machines does it in about six seconds. So the hardware gains are real.
Maybe ML will actually be able to find some optimizations that are too cumbersome for humans to manage.
