Delphi / Object Pascal
RAD Windows client development before .NET. Still runs vertical-market apps whose source lives on a burned CD.
Why Delphi / Object Pascal faded
Delphi faded because the web and .NET ate client-server while Borland stumbled through ownership changes. It stuck in vertical niches — POS, medical devices, industrial — where rewrite ROI never cleared the bar. Admiration survives among aging ISVs; hiring does not.
