This is too often the problem with stuff about Steve Jobs. People worship him, and credit him with inventing everything. So, even ignoring how thoroughly mangled that quoted section is in every way, now he's the inventor of OOP. Did he also invent a time machine to take OOP back to the 1960s?
Jobs:
I had 3-4 people who kept bugging me that I ought to get my rear over to Xerox PARC and see what they were doing, and so I finally did. I went over there. And they were very kind, and they showed me what they were working on, and they showed me, But I was so blinded by the first one that One of the things they showed me was object-oriented programing. They showed me that, but I didn’t even see that. The other one they showed me was, really, a network computer system. They had over 100 Alto computers, all networked, using email, et cetera, et cetera. I didn’t even see that. I was so blinded by the first thing they showed me, which was the graphical user interface. I thought it was the best thing I’d ever seen in my life.
