To add/elaborate systems get complex because the underlying reality is not simple, as much as we’d like it to be. No matter what paradigm (OO, strong/weak type etc.,) we choose or methodology (waterfall, agile etc) we adopt to build the underlying reality can’t be changed or mounded to fit the software, it is always the other way around. Just a few days ago there was this thread about date calculation. One would think how complex can it be? But as one digs deeper they keep discovering layers and layers of special cases. Take Uber as another example. Push a button get a car was their aim. We see people commenting here that they will be able to build it over a weekend. But the real world of cab hailing has thousands of unwritten, implicit rules that are in people’s head. All of them have to be codified and need to work seamlessly, and on top you add constraints of distributed systems and physics etc. Or take tax laws, it’s a labyrinth of rules large enough that people have built DSLs. So, any software that’s solving real world need will be complex. We just have to bite the bullet and deal with the reality.
