"I don't want a Siri that has no understanding of what I'm asking and just does something that is plausible like I asked it to turn off certain lights in the house," he says. "If you say how old is Tom Cruise and it gives you the wrong answer  it doesn't know the answer is wrong and neither do you so kind of like that what the job of a photo is like the job of Siri very often is to do a specific thing that we ask." He adds: "We get frustrated when Siri says here's a web page that I found on that topic but at least there we know we're like oh Siri you couldn't answer it".
