If the brain has a processing capacity of 0.1 whatever it was you said, that is it's functioning speed therefore, following this argument, no the brain cannot exceed this limit. But, then if one wants to take on board the difficulty in ascertaining the power of the brain (contradictory to previous statement in your piece, Mana) well the sky's the limit.
Please get out more my friend!
I suppose it depends on your definition of "smarter." Computers surely can calculate faster than humans can, no doubt about that. However, computers (at least not yet) don't have the same intuitive capabilities that humans have. We are smarter in that way.
some of us are slower than others 
The brain has a processing capacity of 0.1 quadrillion instructions per second.
How do you know?
I don't think "smart" (or "stupid," for that matter) is an adjective that applies to computers or brains.
No. Someone has to switch them on. We can switch ourselves on.
Computers/chess programs are abundant now that routinely beat the best players in the world. It's more of brute force analysis than smarts though.
If a computer and a human were only able to investigate let's say 10 lines in a given position, who do you think would win then? Humans can categorically discard ridiculous losing lines that a computer has to analyze. To me that makes the computer an idiot.
For instance, if I asked a human if he could fly, he would just tell me no.
If I asked Rybka if he could fly, he would spend a few minutes flapping his arms first, and would then tell me no.
@meanpc Haha, I like your comparison.
Currently:
Humans can design and build computers. Computers cannot.
Humans can ponder and discuss which is smarter. Computers cannot.
Computers are missing something that humans have...God.
God reveals a-ha solutions and opens up doors to which computers have no access.
No. Someone has to switch them on. We can switch ourselves on.
Yes! haha
We humans have amazing capabilities that computers can't dream of, for example we are extremely brilliant to identify what we DON'T know. If you ask someone if s/he knows what is the meaning of 'mameluke', s/he will answer immediately 'no' if s/he doesn't know it. Just that easy for us. But ask the biggest database in the world for any kind of information, and it will need time to search the full database just to identify if it has the information or not.
Humans are much smarter than computers, the brain power capacity left for us to use is unbelievable! A computer with equal math facts calculation power must be huge!!! And the final reason why humans are much smarter than computers is that WE CREATED THEM!!!!!!!

That's totally correct! Humans are smarter, and computers are actually extremely inefficient with their computing power! Humans are creating more intelligent computers, and it's amazing what they've created. However, there are a few areas of specialized intelligence that computers are very great at, but if you could even program an extremely intelligent computer, the humans creating it would be smarter. It's a good thought, but at the same time, we cannot let the slightest possibility of that "(ego only for some)" that we're smarter than computers prevent us from attempting artificial intelligence. Why should we fear the possibility of an really really really intelligent computer; it's just a reflection of our intelligence and hard work! We're smarter!
As far as chess computers, it's a genius invention! Rybka can be defeated if we challenge it against Vishy Anand!
WARNING: I am about to seriously over flog this dead horse. This is a TLDR.
I think the general conversation of this thread sums up to this statement:
People have intuition. Computers do not.
As for smarter or not, the way you interpret the definition of 'smart' is just semantics really. I know a lot of people that aren't as 'smart' as a computer. Most people can't solve advanced multi-variable/dimensional differential equations. Computers (with the right pogramming obviously) can. What we should, then, be discussing is whether or not a computer is more or less INTELLIGENT than a human. This is what essentially sets man (and women, if you're one of those overly anal femenist people =\) apart from machine. As somebody previously stated, if a person is asked whether or not they can fly (without aid) that person will immediatly know that they cannot and answer accordingly. It is human intuition that provides this answer for us. Of course that same person could instead DEDUCE that they are landlocked via systematic trial and error. This, however, is inefficient when the answer is obvious. Deduction is the only way a computer can conclude any answer, the consequential conclusion being computers are less intelligent.
Therefore yes, a computer can be 'smarter' than a human because they can always give the correct answer. However they can never be more 'intelligent', because they can never be intuitive.
Not sure what operations per second or whatever have to do with intelligence -- or at least why you'd try to measure it that way... although I know you're not being serious just trolling the forum. Maybe post "what is intelligence" on a philosophy forum and after a year or two of suggested reading lists come back and ask again heh.
Well a computer could analyze more faster but not necessarily better you gotta imagine the computer has to have been programmed to run those quadrillions of calculations but a human can surpass the computer in efficiency and thats what it's all about. The sky is the limit 
Computers have a process of calculating everytime we could just copy what that process of calculating is or do it better but they are faster.
The brain has a processing capacity of 0.1 quadrillion instructions per second. The fastest super computer in the world, called Roadrunner is capable of handling 1.026 quadrillion calculations per second. However the computational power of the human brain is difficult to ascertain, as the human brain is not easily paralleled to the binary number processing of computers. For while the human brain is calculating a math problem, it is subconsciously processing data from millions of nerve cells that handle the visual input of the paper and surrounding area, the aural input from both ears, and the sensory input of millions of cells throughout the body. The brain is also regulating the heartbeat, monitoring oxygen levels, hunger and thirst requirements, breathing patterns and hundreds of other essential factors throughout the body. It is simultaneously comparing data from the eyes and the sensory cells in the arms and hands to keep track of the position of the pen and paper as the calculation is being performed.
While playing Chess is it possible to exceed the brain's peak processing capacity of 0.1 quadrillion instructions per second?
