Apple's Plan to Catch Up to Google and Facebook

Siri seemed pretty futuristic when Apple first released the voice activated virtual assistant. But with Google, Facebook, Amazon and a slew of promising startups pushing the limits of interactive interfaces, the original app for making your phone talk back to you is seeming like a bit of a relic. Leading thinkers in the world of tech are a little concerned. Influential Apple developer Marco Arment wrote in a blog post over the weekend that Apple was falling so far behind in developing artificial intelligence interfaces, the company could fall off the map like Blackberry did. The concern could soon be--and Apple surely hopes already is--irrelevant.
