What timescale are we talking about? Many DOS stock and accounting applications were basically instantaneous. There are some animations on iPhone that you can't disable that take longer than a series of keyboard actions of a skilled operator in the 90s. Windows 2k with a stripped shell was way more responsive that today's systems as long as you didn't need to hit the harddrives.

The "instant" today is really laggy compared to what we had. Opening Slack takes 5s on a flagship phone and opening a channel which I just had open and should be fully cached takes another 2s. When you type in JIRA the text entry lags and all the text on the page blinks just a tiny bit (full redraw). When pages load on non-flagship phones (i.e. most of the world), they lag a lot, which I can see on monitoring dashboards.
