I remember seeing stacks of cards being carried into/out of the university "computing center" in the mid 1980s, on more than a couple of occasions. Though in retrospect, these were probably just old programs that had been in various professors offices since the mid 70s, being taken to get read into some disk in the mainframe.
We still learned how to use them in the 80’s high school computer classes, mostly because we had a balance of CP/M plus card-reader/early DOS machines, eventually .. in the labs. Rich kid schools had Apples though, and some of them also had card readers for BASIC ..
My firt job out of college in the early 1990s was at an equipment manufacturer who was still using them. They had a big chart on the wall titled "punch-card elimination" and a line trending down, but it wasn't at zero yet.
My work there was all new code and didn't involve any of that, however.
The idea that it never existed digitally is obviously untrue. Likely poor wording in the author's part. They probably meant something like, so old that a printout is all that survived (which sounds vaguely like not being digital to someone in an era so far removed from a time when programs were/could realistically be printed.)
> a time when programs were/could realistically be printed
Really depends on the program. Source code is often quite manageable. Even artifacts aren't always as large as you might expect. Busybox on my system weighs in at 1.9 MiB or alternatively 928 KiB with zstd maxed out.
But I don't really see a point to printing any of it. A situation that might require the printouts is likely to largely preclude the continued existence of modern electronics, the ability to replace batteries, or even a connection to a reliable electrical grid.
Yeah, that's why I tried to include both categories. Even for programs that are small enough to be printed, we just don't do it any more. I could have worded that part better myself.
Early versions of some things, MS Basic being one example I think, were baked into ROM. One of the best innovations that Paul Allen came up with was adding software hooks to the code so bugs that were found later could still be patched.
They had some old German guy with a big beard, and two interns, running some sort of big contraption that looked like a medieval torture instrument, and the interns would run and put letters in a row and then the old guy move a massive letter and in the end out came a bit of paper with source code on it.
One has to be pretty ignorant and dismissive to claim that this is not "a big win for paper".
First of all, that comment is weirdly out of place. The quality and longevity of paper is not the topic.
Secondly, there are fragments of paper with writing as old as 2,000 years.
Thirdly, paper you look at and see the writing. With digital documents, you need the technology to read the medium and then you need to know how the information was encoded onto the medium, before you even arrive at the same level with paper, where you can start to decide the actual writing.
Paper has brought us where we are today, and given us what we know about the past. Don't be so ignorant and dismissive.
