That's a very techie view (and I speak as, largely, one:) Core accounting principles don't change so much. Core payroll principles don't change so much. Core finance principles don't change so much. We have a technology-oriented view that "world changes so much", but there are domains where that's true, and domains where that's not true. Several times in my life I had the luck to have a mentor ask me, when I propose some obvious technological change and improvement, "what's the business advantage? If I let you spend X amount of hours over Y days to accomplish technical change Z, in which way will the business be better?" In the world of startups and ___-tech, technology stacks matters and change and it's a whirlwind world of frameworks and languages and webapps stuff. But in the core, back-office, cost-centre business of the company... the rules are complicated and numerous but in a way stable enough that solid stable complex software from 30 years ago still has value.
