John addresses the price of increasing complexity in front-end development.
Yes, tooling can make our life easier. We type fewer keystrokes, and commit more code. But as software engineers learned a long time ago, most of the life of an applications is not in its initial development. It’s in maintaining it. This is something we on the web have had the luxury of being able to largely ignore up to now. After all, how many of the things you build will last years, decades?
