"The Open in OpenAI means that everyone should benefit from the fruits of AI after its built, but it’s totally OK to not share the science (even though sharing everything is definitely the right strategy in the short and possibly medium term for recruitment purposes)." - Ilya Sutskever, in an email to Elon Musk
