I could seriously think that. A pocket calculator has a ~200KHz processor and an LCD with an update time of maybe 10ms. A single digit calculator operation like addition would be a few clock cycles, so say a total time of 15ms with output buffering. A 60Hz monitor refresh rate is already worse than that without considering the framework stack.
- exikyut 9y agoDo you have a source on that clock speed? I've been trying to dig up info on pocket calculators for a while. (The last time I brushed-but-didn't-quite-hit some interesting info was in https://news.ycombinator.com/item?id=15136939 https://news.ycombinator.com/item?id=15136939, which I quoted (very tangentially, as a footnote) in https://news.ycombinator.com/item?id=15153262. https://news.ycombinator.com/item?id=15153262.)
