I hope we someday enter a period of reform where our field begins to apply more rigor to our process. We have the tools to make a fast, sleek web. The process is very, very broken from an engineering perspective. The money seems to never stop, which is why businesses can burn through developers without too much regard to whether they are doing the right things. Maybe that can't be fixed, because the people in charge are going to keep the status quo going if the money is coming in and they're made to look good. Optimization is a risk that companies of even modest size find to be too great.

Or perhaps people involved in a revamp/redesign/unification should be well compensated to the point where they are unlikely to leave in the middle of a multi-year project. I have a feeling based on my experience that a lot of these bad rebuilds are a result of too many engineers and designers coming and going.
