1. Software is fast and UI is instant, things happen instantly
2. UI is instant and software is slow - UI will lag
3. UI is animated with transitions and sofware is slow - people are initially happy, but it wears off in weeks
4. Software gets optimized, now UI animations take longer than getting the underlying data
5. The logical endpoint. Software is fast. UI needs to be instant Remove all animation and let UI render instantly; This is what most users actually prefer.
The parallel with LLM websites is direct imo. We're now getting these fancy websites, but once the magic wears off, everyone will go back to the 'text and links on page' style.
