When Stephen Wolfram is asked, in a recent youtube live stream about [timestamp: 40m16s] "How much of Science has kept secret either classified by the military or waiting for monetization inside private research labs?" he gives a five minutes answer and at the end of his answer [timestamp: 44m] he implies that bitcoin's creator is classified material known to Science and/or secret services.
I don't think that he implied that at all. Here is what he said:
... In terms of what has been kept secret and has become not secret, I would say that the vast majority to my knowledge over the course of my career, .... what pieces of basic science were secret and then became not secret. There are some around nuclear physics. There are some around cryptography. I think essentially all the pieces of basic science are now not secret anymore.
Are there things that companies know about how to do things that are secret? Yeah. There are certainly ones of those, trade secrets of companies and so on, about how to make certain things work. I think those tend to be more matters of engineering of how we, in detail, make this code work, how we, in detail, make this device work, how we, in detail, put these ingredients together in this particular drink, or something. Those are more details than they are basic science. I don't think, but maybe I'm not remembering something. I don't think there is all that much basic science that ends up being kept secret.
I think that people sometimes have all kinds of wild theories about basic science that has been kept secret. I have never really seen any good evidence of those things.
Now, there are strange secrets in the world, like who was the person behind the Bitcoin cryptocurrency and things like that. There are secrets like that, but those are secrets about the doing of things or the details of things than they are about the actual basic science of things.
He started out talking about government secrets, but then he talked about trade secrets, so I don't think you can assume that he was talking only about government secrets after that. He was really just making the point that there are no more secrets in basic science.
I think we can all agree that the inventor of Bitcoin is a secret. But that does not imply that it is a secret known by any government.
