Our Minds Are Easily Deceived... Or Are They?

You've probably seen or heard about optical illusions. They trick our minds into seeing something different from reality.
A few of many examples:

Some say our brains are seeing things the wrong way. I say: our brain is seeing it right. Our brains are powerful pattern recognising machines, filling in details that aren't there, and they're almost always right, except for those anomalies called optical illusions.

But think about this, when computers just became popular we thought we'd have to start by teaching them to do mundane tasks in real life... I mean they must be easy to translate into computer language... right? Well they couldn't have been more wrong. They started out trying to make a computer recognize a bird in a tree, leaving chess as an exercise for later. Untill this day, they're still working on the problem of recognizing a bird in a tree, while the simplest chess computer easily defeats a chess grandmaster. So problems of logic, are hard for us, easy for computers. But our brains are still the undisputed champions at pattern recognition.

So, next time you see an optical illusion, be happy you're not so easily replaced by a computer.
