I think the Java world over-used object orientation in the wrong way: For pretty much everything except creating a good data model. That's why we got InterfaceSelectorAdapterFactory and such. That is, it focussed a lot of effort at abstracting a lot of technical details, instead of focusing hard on the data model, and keeping everything else as simple as possible. Bold was in my view all about a more sane way of using object orientation: To build a good data model. This still holds up as a good way, as we are now (thankfully) moving towards a more data-centric orientation for building enterprise systems.
