I think OOP really took off in industry because it was easy to sell third-party modules. You could "plug in" this module that you purchased and it was easy to hook up. Markets have a way of doing that: the solution that wins isn't necessarily the "best" solution but the one that's easiest to sell.

I don't think the component revolution has happened. We got frameworks to be sure, we even got...gasp...libraries with our languages. Maybe for that reason, OO languages (Java/Python/Smalltalk) were more likely to come without their batteries included. I'm guessing inheritance helped out a bit with that.

But I don't think objects are really especially about third-party reuse or even any reuse at all, but they are more about enabling easy problem decomposition (i.e. break up your problem into a bunch of interacting objects).

OOP definitely has something about it that favors reuse of code.

I think you got it backwards, it's decomposition that it has a problem with - it's not easy to point fingers for exactly why that is (it's probably because of all the mutable state, which leads to entanglement, where components only seem independent of each other, when in fact they aren't), but you can find anecdotal evidence of this happening in the wild ... look at frameworks like Django and Rails, with tons of reusable plugins available and yet a humongous effort went into Rails for making it modular (e.g. such that you can import parts of it, like ActiveRecord, in other non-Rails projects, or for easily replacing ActiveRecord with something else), while Django never achieved it.

I think it happened, but everyone screamed and/or crapped their pants, and ran the other direction.

ActiveX and DCOM.

(shudder)

[bad_user]

I think ActiveX/DCOM is a good idea that was badly implemented.

Surely you mean "WITH their batteries included"?

For this is the very situation in Python (and it's slogan in fact), and of course Java has the most extensive "included batteries" in the form of the JDK API than any other language.
