People overestimate the speed of the spread of computers.
I didn't have a computer where I worked until 1994. And then, it was shared by eight people.
At my next job in 1995, I made them buy a computer for the office as a term of employment. At the time, I suggested that a laptop might be a good option, since the computer would be shared by three people. For the next two years, the sales guys made fun of me for wanting to put a computer, and for wanting one that fits on my lap.
I later heard that when I left, they sold the computer. I wonder how those blissfully computer-free sales guys are doing today.
When I worked for Westinghouse in 1996 was the first time I was in an office that has one computer per person. But not every department had computers at all. And most who did were just terminals hooked up to a Vax in accounting.
When I worked for a large regional media company in 1997, everyone had a computer. Only a couple of them had internet access, and that was only e-mail. This was during the days when so many people were getting AOL at home that it became uselessly bogged down by its own popularity.
1999: Everyone in the office had their own computer. Not everyone used them. But at least they all had internet access.
(OT: I'm sad that the macOS spell checker didn't know the word "Vax" just now)
