At university, we were forbidden from using Excel, and only FORTRAN 77 was allowed. At the time, this seemed strange and anachronistic, but when you consider that it had been in use for 25 years at the time, and was a known quantity that didn't have strange and unknown bugs, it actually seems sensible in retrospect.

I do however recall being mightily annoyed that I was having to calculate ephemera in "arcane bullshit", so I can understand why many shortcut to excel.

Experience makes fools of our past selves.
