It's because majority of us have no real problems to solve, so we do what everyone else is doing in the corporate world and make ourselves useful that we can keep collecting paychecks. Best way to do that is by over-engineering solutions to problems that are already solved.

Or we can replace perfectly functional systems simply because replacing legacy systems with modern solutions has some intrinsic value on its own, even if the modern system brings no additional value.

There are bunch of real problems that could be solved with software, but there's no money in it so why bother? It's better to roleplay technical expert and collect consultation rewards doing nothing.
