Microservices in big companies where you have to first write the spec and then fully understand the changes is maybe among the least benefiting use cases yet.

Microservices in big companies where you have to first write the spec and then fully understand the changes is maybe among the least benefiting use cases yet. When you work on just a new mobile app, this is where I find AI is making the biggest difference. On mobile you don't need specs and you don't need to understand every detail of the implementation. You can QA test the app on a real device. It gives me more confidence than just having written the code myself, and it's much faster. You can implement multiple major features in a single day. This kind of e2e testing is just not possible with backend services.
