I believe object-orientation is dated

I don't know how many advances might be happening recently on some underground Smalltalk mailing-list, but in general, OOP has remained the same for decades.

Does everybody think it's good enough? Does nobody want new features that will make your code more expressive somehow? Watcha think?

OO is one way of designing your system. It has strengths and weaknesses for different types of problems. You're supposed to use OO design when the strengths of OO design to the problem are more valueable than the weaknesses of OO design to the problem.
