>> they simply used the computer/Excel to automate what was previously a manual process.
No. I do know both what they were doing and why they were doing it. Neither of which have much bearing on why they wouldn't change it.
The main driver to most of their behaviours was their insular attitude. They did not accept that they needed to pay attention to anything outside their own world.

Actually not. 3.5s came in in the early 80s and were in general use by 1990.
