I liked this analysis a lot.

However, OpenAI is a bad example of the future vision paradigm. In fact it fits 1/6 of the characteristics they identify in this paradigm. A better example would be something like Tesla.

I would say OpenAIs backing of the GPT model family in itsself is a better example of the future paradigm than anything to do with OpenAIs founding or non profit status that sequoia discuss. Going all in on GPT gave them a big headstart (although google should have been fighting much earlier if they had listened to internal researchers).
