I’m curious how software can be created and evolve over time. I’m afraid that at some point, we’ll realize there are issues with the software we’re using that can only be remedied by massive changes or a complete rewrite.
Are there any instances of this happening? Where something is designed with a flaw that doesn’t get realized until much later, necessitating scrapping the whole thing and starting from scratch?
In reality this happens all the time. When you develop a codebase it’s based on your understanding of the problem. Over time you gain new insights into the environment in which that problem exists and you reach a point where you are bending over backwards to implement a fix when you decide to start again.
It’s tricky because if you start too early with the rewrite, you don’t have a full understanding, start too late and you don’t have enough arms and legs to satisfy the customers who are wanting bugs fixed in the current system while you are building the next one.
… or you hire a new person who knows everything and wants to rewrite it all in BASIC, or some other random language …
