I like to think of the example of open source software development, or mainstream sites like Wikipedia that allow the people at large to update information at will, and seed out vandals. Humans are fallible in emotional/logical ways that a Machine would not be. At the same time, the AIS is fallible by the simple inadequacy of it FULLY capturing the entire range of every mental/emotional/psychological impact of natural occurrences – from a mad girlfriend, to the effects of a tsunami, to why your college roomie likes to play the Black Dragon calypso album five times a day. The Machine, for all its exposure to the world, cannot know what people think – only what we do. So, tweaks in its activity can be monitored and adjusted by a world at large – much better than trusting the maintenance to a possibly megalomaniacal techno-whiz who might want to take out the planet because he hated his daddy. ;)

A possible serious weakness to AIS is its adaptation to a world where it becomes more and more dependent on its use, from medical use to financial markets to solace for lonely, desperate people. In the Great Depression, people so dependent on the old stock exchange during the crash literally killed themselves. When the World Trade Centres were smashed down, the stock exchange similarly was affected.

We all know what possible consequences are if a massive blackout nullified even the back-up systems of hospitals, heat and light, even food and water production. And many people now live out their social lives via the Internet (see the perp who almost succeeded in a mass suicide with lonely female members of his chat group.) In the event of a cataclysmic system crash for a fully-integrated, fully-indispensable worldwide AIS, all of could become instant bedlam. So, the social importance of an AIS in that scenario would have to be very closely monitored by thinking, reactive humans after all. We will still have to use our good ol’ noggins, because you can’t eat or drink silicone chips, and what good is a mechanical AI heart in your chest if it stops working?

One more point about the implications of a fully-functional AIS, and this stretches to religious and spirituality. All of the world’s religious texts were written by the hands of men. Whether the belief in God came through divine revelation (as the religious/spiritualists like me believe), or simply through man’s childlike imagination (as the atheists attest) is a history-long argument between these two groups.
