That's true, but the point the GP was getting at is, if you want to make a program that does xyz, you can do that in any complete language provided you have the mathematical reasoning to figure out how to make it happen. Whether you do that in an object-oriented manner because the language you're using makes that easy, or with some other paradigm.
Programming in a language is finding what works in that language, you're right, but programming at all is trying to get what's in your head into the computer.
