This document discusses the author's experience with Ruby on Rails over 10 years. It outlines both the benefits and drawbacks of Rails. The good parts include how easy it is to build prototypes, get help online, and find jobs. However, Rails can also make developers overly reliant on its frameworks, opinions, and gems. This dependence limits learning and flexibility. The author advocates learning first principles, stepping outside comfort zones, and understanding underlying technologies like SQL instead of just using Rails as a black box.
