I think if we can have a good enough simulation of reality, and a fast one. Something like an accelerable minecraft with real world physics. Then this idea might actually work. But the hard reality we currenly could generate efficiently and

True, and the successful ones usually require an external source of information. For AlphaGo, it is the simple algorithm which decide who is the winner of a game of Go. For GAN, it is the images labled by human. In these scenarios, the cri

I also hope we have something like this. But sadly, this is not going to work. The reason is this line from the article, which is so much harder that it looks: > and a critic model filters the results for genuinely valuable ideas. In fac

Some additional context here. The author has a further statement, in which he apologizes that the previous video was misleading due to two points: 1. The sample was not LK99. 2. Both the larger piece held by the tweezers and the smaller lev

I guess it really depends on what you are working on. If you are writing some non-trivial algorithms or working on some projects which requires delicate handling of things, then Copilot is most likely going to mess up. But if you are workin
