> We have a single developer taking care of the codebase. Does Optimizely need ten people to handle theirs? Or twenty? We don't know, but one thing is for certain: 20 people make more redundancy, technical debt, and bugs than one. I get the point that having too many developers writing too much code can make it too much to handle. But I've seen what one person operating alone in a vacuum can do as well, and it is not pretty. It seems like really you want maybe 3 people to really understand some code. That gives you a good bus factor, but not so many people injecting ideas and patterns that the code becomes unwieldy. More important, it gives you extra code reviewers who can push back against bad code smell and hopefully find bugs, or at least try to test it. 1 might be better than 20, but 3 is better than 1.
