Earlier quoted context omitted.
The industry used to be able to ship shrink wrapped software that a non-technical person could install on their home computer, without 24/7 instant messenger support to get working. I think B2B software should be able to create manageable installations for technically competent IT professionals.. If your install has that long of a manual task list, your cloud SaaS infra is probably junk too.
You’re thinking of a time when only “computer geeks” could install and run the software of their choice. When every office had fleets of IT admins to install the pre-approved applications people needed for their day-to-day. Back then, learning how to manage your own PC and install software was tantamount to earning an IT certificate. Doing so for a few years in high school would be enough to qualify you for a career…
Perhaps not thinking of a "time when", perhaps thinking of an OS that required an IT certificate.
Because even early Macintosh System Software (classic Mac OS before OS X) was bewildering to Windows users, since any user could "drag" a program from a floppy disk onto their hard disk, leave it anywhere, and it worked.
Arguably, OS X introduced the Applications folder in 2001 partly to give people a place to drag things to and feel more comfortable that's where they could find their "Program Files" (but mostly so multi-user system users would get to add and re-use apps in a common clear place they "should" be).
But you still didn't need an IT admin.
