The members of an ant colony work together as if they were a single organism. The human brain has neurons that work together in the same way: one neuron is not "intelligent", as such, but a whole lot of them acting in unison make us what we are. The secret is communication, connectivity and the processing of information. In the modern world millions of people are communicating with each other in almost real time using Twitter, SMS, Facebook and other social networking tools. If a billion people are doing this and we think of each person as a single neuron, does it mean that we starting to create some kind of global intelligence?
Based on the average tweet, the global intelligence level would seem to be somewhat low at the moment and the same could be said for the content of many websites, blogs and social network pages. A lot of work is being done on machines that simulate the action of neurons in the human brain. There have even attempts to "teach" machines how to "learn" for themselves. It is estimated that some time in the next 50 years or so, enough processing power will be available in a notebook-size computer to simulate the number of neurons in the human brain which could _ theoretically _ allow it to become self-aware. So, apart from Skynet, where is this going? We could be on the verge of creating new forms of life and it might even happen in the lifetime of some Currents readers.
In recent testing, the iPhone 5 came seventh out of seven smartphones tested. Which? magazine used the Geekbench 2 test suite on the Samsung's Galaxy S4 and Note 2, Google's Nexus 4, the HTC One, Sony's Experia Z, and the BlackBerry Z10. The Galaxy S4 came out on top, judged as being over 90% better than the iPhone and 14% better than the No.2 phone, the HTC One. Of course, the S4 has a quad core 1.9Mhz CPU compared to the iPhone 5's 1.2 GHz dual core and we will need to see how the iPhone 5S performs when it finally appears, but the S4 will be hard to beat, especially with a new 2.2 GHz CPU coming out soon in the new version.
