Although Eliza was coded for a less powerful machine, the most powerful mainframe in existence in 1964 was the CDC6600, which was able to put out about 1 MFLOPS. The iPhone 4S is apparently capable of 138 MFLOPS. ( http://www.phonearena.com/news/Apple-iPhone-4S-benchmark-tests_id23140 http://www.phonearena.com/news/Apple-iPhone-4S-benchmark-tes... ) We've managed to put the equivalent of hundreds of room-sized mainframes from Eliza's time into something that can fit in your pocket but, in the last 47 years, A.I. has advanced so little that Siri is using the same bag of tricks as Eliza. All that distinguishes Siri from Eliza is some licensed speech recognition software, a nice collection of pre-programmed geeky easter-eggs, and the fact that Siri is plugged into a collection of apps and search engines that allow it to perform a few basic, but useful tasks beyond simply fooling around. However, those tasks do not really require, or make use of, A.I. at all. Google's voice interface for Android makes no pretensions towards sentience, but is capable of everything Siri is. Google just hasn't wrapped their voice interface software up in a cute anthropomorphized Eliza wrapper or taken the app integration as far yet. That, and perhaps a little interface work, is pretty much it. It is simply astounding that, in spite of Siri having access to such vastly superior resources, Eliza still comes across as the smart one!
