When MacOS wants to nag you it pops up a Liquid Glass vandalized version of the 1999 retread of the modal confirm dialog from the 1984 MacOS.
I wish both of them had NEVER OPEN A MODAL DIALOG THAT I DIDN'T ASK FOR EVER AGAIN button that took 80% of the space and a tiny little greyed-out link at the bottom that said "maybe just maybe I want to hear about this in three years" but from a graphic art viewpoint I laugh at MacOS.
Nonsense. The best experience is the one that solves user’s issue. Technology choice is orthogonal to that.
Slack is, in fact, one of the worst offenders. It is so incredibly sluggish. And it doesn't need to be, when I compare it to the speed (and memory consumption) of Pidgin with the Slack plugin.
That is, uh, controversial.
Along both "alleged replacement" and "alleged superiority" axes.
