Then you'd have IBM AS/400 :) Those things are used in airline ticketing, certain large grocery stores, semiconductor fabs and manufacturing MRPs systems for WIP tracking, and logistics industry - when you need speed and no bullshit. It is archaic but works faster than any Javascript app you can build. IMO this is a very underappreciated UI that needs more praise. Intel's, Global Foundries, TSMC factories (fab + assembly) run on IBM AS/400 I believe. I have anecdotal information about large companies switching to contemporary systems with nothing but dissatisfaction from the employees that actually use this system, 8 hours a day for many years.
