You're right about those things, but you're forgetting that we had no source control, and almost all software was closed source. You took what you were given and you liked it, and you developed strong attachments to particular versions of software which you clung to well beyond its use-by date (like Python 2.7). MS-DOS 3.3 forever!

We had version control in the 70s with SCSS and then RCS. They were primitive, but a lot of software were only a few files.

		In the 80s, source control was like networking. Yes some orgs had it (mostly academia) but the rest of us just had a precious floppy that we copied the known-good source onto.
