Soohoon Choi argues (as do I) that AI will lead to better code (via Simon)
AI will write good code because it is economically advantageous to do so. Per our definition of good code, good code is easy to understand and modify from the reduced complexity. This means it requires less context to understand a relevant piece of code and fewer lines of code to be written to achieve some change. Translating this to token economics, we can clearly see the parallels: it is more token efficient to write and maintain software with good code.
The economic argument is interesting, I think there are multiple other arguments. In the Laravel world, for example, the framework now ships with AI guidelines, which means that the average new code in the framework will much more closely follow best practices. Better code!
