Weird take. Tech boomers started with tape or commandline. The ide only became the development environment of choice in the late 90s, firmly with genx and millennials.
Claude code is a terminal interface not a command line tool. More like vim than sed.
Visual BASIC was 1991. QuickBASIC, Borland Turbo Pascal, SmallTalk-80, NeXT InterfaceBuilder, all pre-1990, several well-pre-1990. Boomers absolutely had, and indeed devised, the IDE.
