I have mixed feelings about RoR, having seen both sides: the incredible speed of development as a startup bootstraps its MVP, and later as a mature company where the codebase becomes an immense behemoth of tech debt that's almost impossible to refactor. Don't believe the people who handwave and say you can avoid the latter by just "designing it right at the beginning". That's a lie, even the best engineers will build an unmaintainable monolith in RoR given enough time and if the business requirements are complex.
At this point I have a strong aversion to starting any product using a dynamically-typed language (regardless of framework). The initial speed and ease of development is repaid 10x later on in sheer engineering pain (if you're lucky enough to be successful, that is).
I will support the most extravagant and unnecessary new aircraft program the MI complex wants to push forward, PROVIDED that the resulting machines stay exclusively on US soil and in US airspace. Versus immediately being sent thousands of miles away to defend Israel, Europe, Japan and/or South Korea.
Wow. Racist much?
