I'd say one property of good ideas is that they are able to survive much longer than bad, so, yes, they have a higher probability of reaching a general consensus. Bad ideas can also reach consensus. Consensus is not always an indicator of quality, and I don't believe good ideas are destined to reach consensus. I can't really argue with the historical impact of OO, because it's obviously had a ton. OO is always so loosely defined that a no-true-scotsman argument is almost inevitable, but I'd certainly say a subclassing model is one of the defining features of the OO languages we talk about.
