Successful as in slow to use, poorly designed, difficult to extend and a memory hog. You can't even reuse code between rails1 and rail2. OO is a joke. Pure OO languages like Java and SmallTalk are already failures. C++, Scala, Kotlin are not OO languages. Design patterns are not engineering, let alone architecture.

The only success for OO has been UI development. It's a failure everywhere else. OO databases are a failure. ORM is a failure. OO based distributed computing has failed, we use REST. OO based design is a failure, no one uses UML.

OO based architects are a waste of time and money. You can replace all OO based architecture nonsense and patterns with code written in Go.
