Almost everything on computers is perceptually slower than it was in 1983 (2017)
Said this already but worth repeating:the best computer application I interacted with was an AS400 era tax filling system.It was a superb tool in the prettiest meaning. It was a care free, lag free, pedagogy free thing. Fill out data as it comes (the only smart key you needed was tab and shift-tab), smarter than the average web app form validation checks and suggestions. Think instant Elm typecheck where you enjoy the computer assisting work.I was in 4th year in college and blown away how this thing beat anything we'd see or studied in school yet it was antique pre-OO pre-UML (maybe an ancestor of modeling hygiene though). I wish I could have a talk with the team who wrote that.Of course it was about to be replaced by a web2.0 variant which was a resource hog, required constant scrolling, didn't do half of the old work but was full colored css.
