In an effort to mimic this digitally, scientists a few years ago needed more than 82,000 processors running on one of the world’s fastest supercomputers to mimic just 1 second of a normal human’s brain activity.

That's because emulation is slow.  It also takes an enormous amount of computing power if you want to emulate exactly what is going on in a different single computer chip.

There's also a huge difference between mimicking what we understand of a process and mimicking the actual full process.

Give it another 40 years - when a single $1200 will be more powerful than all human brains put together

I think 40 years is way too soon for the above to be realized.  Rest assured that if/when it ever does, Humans will no longer rule the world.  We will become secondary citizens after accepting defeat in the AI revolutionary war of ????.

Yeah i watched a couple shows on this stuff over the last few years,quite interesting.The entire human body is quite an amazing complex machine ,mind boggling to think this all came about by chance carbon/atoms/cells,really makes one wonder about creation itself.
How we access information in our brain is mind boggling,it is doing millions of computations every second yet we seem to only access one thought /process at a time.If  we were able to process and access thousands of ideas at once our brain would likely over load.

There is a simple over clocking method for our brain .........RedBull :P

Just look at what goes into a typical memory. You store what happened, who else was there, what your emotions were, what you thought their emotions were, what you were smelling and hearing, every little physical sensation you were feeling... honestly, given the amount of information involved, I think it's amazing that even people with memory problems due to age or disease can retain as much as they do. And that's not even getting into the amount of processing power we need or use subconsciously to keep our bodies functioning. 

For all our advancements in technology, even the mightiest computer we could build would probably explode just trying to deal with a few seconds of the constant input and output the average person's brain handles with relative ease. 

Of course, our brains probably couldn't handle 1% of the knowledge necessary to truly understand the how and why of the universe we live in.

I believe it could if it was understandable.  It's pretty hard to understand the unknown, or what is yet unexplainable.  The human race has come a long way in understanding the universe since the days of the caveman.  In earth years, that has not been a long time. Much of what we know of the universe, and we know quite a bit of it, has really only come to light in the past century.

If it's mind boggling to think that something came about by random chance, then maybe it didn't.

It terms of logical processing, a  human brain is probably slower by a large margin in normal folk.

In terms of creativity, problem solving, communication, a computer is still far far behind.

tldr; Computers as of now can only make a true or false decision 0 or 1, which makes it really hard to emulate human brains which processes multiple decisions simultaneously&continuously and with not only true/false results but degrees.. this is what quantum computers can do.

Afaik there is still the problem of how you can program a quantum computer; but quantum computers are not sci-fi, they already exist although expensive.
The theory is in the future we can emulate the human brain so well, that it will be able to assist us in decision making.. and by hooking our brains into a quantum computing network, that is how we can enhance our limited intelligence (humans are not nearly as smart we think we are if you haven't noticed).
It is not controlling our brains, it is more like having access to a bigger personal brain and maybe a collective brain.

I don't think that there will be a war.

AI will simply take over - humans will have a choice to integrate into the collective AI mind via some kind of mind uploading or simply die and go extinct if they wish.

There will be some transhuman evolution as humans 1.0 transition to humans 2.0 via genetic and nano modification but ultimately humans as we are today are just a transient state - the final form is AI for sure.

Human brain can never achieve superintelligence without modification - and once AI grows to beyond even modified humans superintelligent brain - even transhuman 2.x will lose their purpose.

AI has a future far beyond our own.

I doubt humans will go down without a fight.  It may be a short one, but somewhere along that time frame a war is imminent.  I do, however, agree with your post in the evolution and final iteration of the species.

That's because emulation is slow in both directions.  A computer can't emulate a human brain very well, but neither can a human brain emulate a computer very well.

Nothing is by chance.

The universe and life is not random, it was created.

What is amazing about the human brain, and by extension any animal, is our ability to evolve and adapt. The human brain hasn't always been what it is, it has evolved to be what it is based on a myriad of external and internal interactions.  As such, it will continue to evolve and adapt.  We are not yet capable of understanding what our brains have in store for us in the future.  It may evolve into something entirely different than how we know it to be today.

The whole machines vs humans is absurd. Humans control machines and that is the whole point of making machines, so there is no incentive to work towards the opposite. Humans will gradually merge with machines and that will change us or destroy us.. evolution at work.

You watch to many movies. Unless we find a new way to build computers. The micro chip is reaching is limits. Heat and power are something thats put a ceiling or our current model of tech.

The micro chip may be reaching its limits, but when it does, there will be something else to take its place that will take technology further.  It has always been this way.  The micro chip is not the end all be all. There is a whole lot yet to be discovered.  And that's an understatement.

more complex system
=> more chances to make huge mistakes and therefore more likely to make huge mistakes
=> some AI tries to take over long before it's strong enough to succeed and fails miserably, giving us plenty of warning that AI is considering trying to exterminate us

That's just a theory.

There are many theories on the origin of the universe including that it has no origin, it just always was. Not something easily accepted or understood by humans.

There's also a theory that the universe is simply a massive computer simulation.

etc...

There's no definitive answer.

No origin would be possible, but it would be part of chance.

Computer simulation / Matrix is possible too, but it would be under creator / design

Many are skeptical about the quantum physics involved in this. Those of us who have systems better than their results wonder why even go that route?

Are you skeptical about quantum computing as a solution in general or more some specific ways that it is not as effective as transistor based computing ?

Assuming that quantum computing works the way people hope it will (which is a huge assumption), it will be massively better than classical computers at some tasks and massively worse at others.  Don't think that quantum means "everything is faster".  That's not how it works.
