I find it very hard to agree with thesis when there is absolutely no backing information about how OO programming is "hard". What are the difficulties people are having with OO? How can I take this article seriously when it's nothing more than a statement followed by some fluff followed by a few half-thought suggestions. Who are these 'people these people who 'really understand' OO programming? Am I one of them? Are you? How are we to know with no example of HOW OO is hard? What exactly is so hard about it? Class Apple extends Fruit. apple = new Apple(). apple.eat(). Makes sense to me. How are people using it wrong? Is the real issue that people don't understand when to use it? Here's a similar article: Playing poker is hard. A lot of people really don't understand how to play poker. People that play poker should stop, and start playing go fish. They should leave poker to the professionals that understand poker. All poker books should now become go fish books.
