Now, imagine a scenario of a typical SWE in todays or maybe not-so-distant future: the agents build your software, you simply a gate-keeper/prompt engineer, all tests pass, you're now doing a production deployment at 12am and something happens but your agents are down. At that point, what do you do if you haven't build or even deployed the system? You're like a L1 support at this point, pretty useless and clueless when it comes to fully understanding and supporting the application .
This is why I suggest developers use the free time they gain back writing documentation for their software (preferably in your own words not just AI slop), reading official docs, sharpening your sword, learning design patterns more thoroughly. The more you know about the code / how to code, the more you can guide the model to pick a better route for a solution.
