The internet is fast. Computers are fast. One second is enough time for my machine to download 10M data points and render them into an interactive plot.

In my mind, anyone doing UI development and seeing user interactions taking over 1 second should be asking themselves "did the user just try to operate on more than 10^6 of something?" and if the answer is no, start operating under the assumption that they've made a mistake.
