The line of code that saves the most time is the one you don't write.

It's all contextual. Sometimes, particularly when it comes to modern frontends, you have inescapable boilerplate and lines of code to write. Thats where it saves time. Another example is scaffolding out unit tests for series of services. There are many such cases where it just objectively saves time.

Reason went out of fashion like 50 years ago, and it was never really in vogue.
