I'm a fan of OpenAI, but this is nonsense. All of human existence is mostly other people's ideas. Among a ridiculously huge list of other things, OpenAI benefits from the mountains of labor that made scalable neural networks possible.
Have they had their own good ideas? Definitely.
Are they benefitting of ideas mostly invented elsewhere? Also Definitely, just like everybody else.
