So I guess I can only run ~16 instances of Slack. Damn...

But that implies you _only_ run Slack.

That means a $1k+ computer with Linux can only run 16 Slack instances. If you're on Windows and aren't as wealthy, the count goes down to 5.

Soon you have to micromanage your computer resources instead of purely focusing on work.

~5 Slacks! Oh, my! How will the proletariat survive?!?!

And yes, obviously if your computer is less powerful you can do less with it. Are you trying to argue that computers are classist because they don't work the same for poor people?

My 1st point is the same everyone criticizing performance bloat is trying to make: running our software in such inefficient way, even though we can, is not good. We could accomplish way more for the users if the underlying stack didn't by default eat so much of our performance budget.

The 2nd point is simply that unless you're only targeting upper class and tech savvy users, 16 free Gb of RAM will not be your baseline.
