Human brain vs Computer

Today I had a discussion about "brain vs computer" with my friend. As like most people, he argued that brain is capable of making more complex (literally unimaginable) decisions. I argued that brain seems to be complex but actually it is not too complex as everyone would think of. I have some points to suppor my arugment from my own day to day oberservations. Here are my points.

The main reason why humans seems to be unpredictable (and so called complex) is that no one knows what logic other humans have at any given moment.But computer logics are static and well documented and can be verified if needed.Humans create lots of logic each day and delete old logics if needed.

Humans have the tendency to automatically add/delete logics to their decision-making circuit with every good or bad experiences. But computers do not. We need to add the logic to computer code whenever we need.

Analysing this furthur, the EMOTIONS are the one that create this logic in human brain.

For instance, a child has no idea of a 'fire' or 'heat'. The first time a child touches the fire the following sequence happen

• --> The sensors in the skin sends 'pain' signal to brain.
• --> The brain experience the 'pain' signal as actual 'PAIN'
• --> The brain sends emotion of fear/aversion towards the pain causing 'FIRE'
• --> New logic coded in brain like

if(FIRE == true) {

keepoff();

}

Second example, a teenager looks at a beautiful girl (in his perspective). Following sequence of events happen.

--> The eyes send 'Beautiful sexy chick' signal to 'brain'

--> The brain experience the actual 'BEAUTY'

--> The brain sends emotion of 'love/lust' towards the cause i.e. 'the girl'

--> New logic coded in brain like

if( youMeetThatChick() == true){

tryDating();

}

Now, we can imagine how many new logics added to brain each day.This is how on seeing any emotional movie we make up our mind to do something about that.Say you see the documentary 'Inconvenient Truth' and you feel that we should reduce pollution levels and GO GREEN.The reality beind is that on seeing the documentary movie you got 'fear' about environment and you have written a logic like...

if('any of my acitivity bad for environment' == true){

try{

stopDoingIt(my.currentActivity);

} catch(unableException ex){

tryLimiting(my.currentActivity)

}

}

SADLY, the computers simply cannot do this logic addition themselves. We need to write this kind of code in them !
