The toaster example is relevant. It is a physical thing, like a particular git repo would be, too. In contrast, an idea is not relevant. It just happens that in US, ideas are patentable - which is nonsense. A nonsense that you happen to agree with. Yet you contradict yourself - on one paragraph you want to protect the implementation, and in another you wish you could protect the idea.

I'm not stuck on the title, and I know just as little about AI as only there are strong and weak forms of it. But if I happen to look at Star Trek tonight I should not be allowed to go and patent 30+ "ideas" that I saw in that movie or that I dreamt of.
