To be honest, I first learned about using spreadsheets because my mother worked in insurance - not as an actuary but as one of the people under the actuarial department. Lotus 1-2-3 was the norm not only for that office but the industry. As she was retiring, Excel was becoming big (because the standard OS moved from DOS to Windows), and Excel was just starting overtake Lotus. When it's been an SOP for more than 30 years to the point that they can reliably teach the basic use of these sheets in colleges/universities? You're not highly likely to shift it in an established corp.
