Is there a better example of natural selection in action than 'Project Runway?'

Cloud computing offers individuals access to data and applications from nearly any point of access to the Internet, offers businesses a whole new way to cut costs for technical infrastructure, and offers big computer companies a potentially giant market for hardware and services.

But here's the ugly truth: nature doesn't care about democracy, or who's right, or what's fair. And because of the slow-change aspect of climate, we can't wait until the worst effects are upon us to make a decision -- by then, it would be far, far too late. The scenario we may be faced with is one where doing something for the wrong reasons, run by the wrong people, may still save more lives than holding out for a more appealing option.

Many of the cognitive enhancement drugs serve to increase focus and concentration. But 'letting your mind wander' is very often an important part of the creative process.

My own suspicion is that a stand-alone artificial mind will be more a tool of narrow utility than something especially apocalyptic.

I have to admit it: I'm not a huge fan of the cloud computing concept.

Don't expect to be able to upload your cat's brain into your Roomba any time soon.
