Agreed that you shouldn't design for changes that aren't extremely likely to happen. Ends up overcomplicating things with abstractions on top of abstractions.

Agreed that you shouldn't design for changes that aren't extremely likely to happen. Ends up overcomplicating things with abstractions on top of abstractions. And then when a change does come it often isn't even expected and doesn't fit into the abstractions. But because everything is so convoluted, you either need to make a large code change to fit the new feature or you need to put a hack on top that completely invalidates the abstractions.
