I wasn't saying Steve Jobs was self-promotional like Wolfram, but a lot of Apple reveals involved 'incredible, never-before-seen' sorts of language. Language like "as far as I know we're the first people to ever do this" seems like the kind of thing Steve would say about a product; these guys are just applying it to a project they worked on.
If I'm honest, I'm probably just very cynical about any sort of salesmanship.
