s/objects/classes/

Java insist putting everything in classes for "OOness" sake, but still have "primitive" (non-object) types and no first-order functions. AFAIC, Java is a braindead language. Too bad everyone and her little sister confuses OO with Java - this greatly deserves OO IMHO.

Lol. But note that Simula was about, well, simulation - which may explain this trend...

Agreed. But see above.

Agreed again. Most of the damage comes IMHO from dummies trying to teach ununderstood OO to other dummies - with of course dumb examples in dumb languages.
