Through a happy set of circumstances the two guys who started Siri visited my house a few years back to show me their new tech (I was one of the few journalists who covered this startup and during the interview I said "I bet you're gonna get bought." Sure enough, Steve Jobs bought this company after only a couple of weeks on the market in a deal rumored to be more than $200 million.
No actually, I think it is the opposite. In the strict sense of the word, i.e. in the dictionary as well as the legal definition, his activities very much fit into the definition of invention and inventiveness. Steve Jobs however does not fit one stereotype of an inventor, i.e. the "nutty professor", a nerdy technician who is good at computation but bad at social interaction. Invention can take place at many levels of technological maturity. In any case Steve Job was very much involved in decision making and idea generation at the micro/lab level. His technical understanding of the guts of computer science, both hardware and software, is not to be underestimated. He was far more technically competent than say John Sculley and has his hands dirty in both his tenure as CEO. He was much more of a technologist than Bill Gates, simply because he was more interested in the technology than the business. Actually you would be hard pressed to find a CEO of a large tech company as obsessed with technical design decisions as Steve Jobs.
