Despite advances in technology, computers still can’t come close to the power of the world’s most remarkable computer – the human brain.

Computing machines have seen three phases: the tabulating phase, the programmable phase, and now the new era of computing, the cognitive phase [1]. Tabulating machines performed a fixed task, whereas programmable machines could be reprogrammed to execute different tasks without any change in the hardware. Cognitive machines, however, promise learning and reasoning capabilities.

The possibility of such machines raises the question: is cognition the ultimate test for conscious existence? What do we know about cognition? How do we define intelligence? The questions go on and on. One thing, however, everyone seems to agree with is the fact that understanding the mechanism of human cognition is the key to developing advanced artificial intelligence, and cognitive machines.

Cognitive machines have the ability to learn, and they employ artificial intelligence to “reason.” Artificial intelligence is defined as, “The science of making machines do things that would require intelligence if done by men” [2]. The good news is that cognitive computing is no longer an esoteric pursuit of some futurists. It is, and has been, essential for the operation of many big-data driven processes. The 21st century has been flooded with data coming from almost every aspect of our lives. Technology has made it possible to generate data at an exponential rate. Temperature distribution throughout our buildings, the number of people diagnosed with cancer in the last six months, real-time changes in customer preferences, ethnic profiles of college applicants, and the top three words trending in online conversations at this very moment, are some examples of the kind of data available today.

As the amount of data generated increases, it also becomes harder and harder to process and make sense of the data collected. Our “greedy and ambitious” human nature does not want to waste, and it wants to use every bit of available data. This is where it becomes imperative to have a computing machine that goes beyond performing pre-programmed tasks and learns as it goes, without human interference. For this kind of computing, we need cognition.

The biggest challenge in imitating human cognition is to understand how cognition happens in the brain. It is obviously beyond our ability to monitor such activity that is constantly taking place in our brains, let alone recreating such marvels in the first place. Nevertheless, it will be a great achievement if we can manage to somewhat imitate human cognition, even partially. It would open a whole new era in terms of what can be achieved from a computing standpoint. For instance, the entire curriculum of a college degree can be processed by a cognitive machine in a fraction of a second; such machine can digest the whole of medical literature in a short period of time, provide human doctors with second opinions on their diagnoses [3].

Despite the fact that there have been substantial improvements in designing “intelligent” computing machines, mimicking the hardware of the human brain and simulating its decision-making processes, have posed three fundamental challenges: a hardware with comparable processing power and memory, a software algorithm to implement intelligent behavior, and the necessity of both being self-adapting and self-improving.

First of all, human intelligence has not been fully characterized – its capabilities and limitations are still unknown. This lack of knowledge makes it difficult, and perhaps even impossible, to reduce such intelligence to smaller, or simpler, modules. Therefore, we don’t have a good handle on how to mimic the human brain in a behavioral sense.

The second major problem is that we are still far away from having the hardware on which our “intelligence” software could run. Implementing intelligence in conventional computing machines, evidently, seems to be a futile undertaking. Programmable machines are no match for human brains; even the fastest supercomputers, taking advantage of thousands of processors, is able to mimic just one percent of one second worth of human brain activity-and even that takes 40 minutes [4]. Therefore, cognitive computing machines must incorporate different hardware architecture from conventional computers to achieve cognition comparable to humans. IBM’s SyNAPSE chip is one example of hardware inspired by the brain, and it has the potential to carry out the required, intense computations.

Lastly, the human brain and its cognitive power are constantly changing. Depending on various factors and experiences, our brains can improve or deteriorate; this is also true of our cognitive power. However, such improvement or deterioration could be in the form of a change in the physical structure or the amount of capacity utilized [5]. Such dynamic flexibility, also called Brain Plasticity [6], is essential to our intelligence. At this time, no self-evolving computing hardware has been worked out. However, promising developments have been reported with respect to cognitive computing machines that can learn – that is, they can make deductions and reach conclusions that are not preprogrammed.

Along the way, human supervision will be the ultimate guide in perfecting such imitation. Therefore, human cognition, taken for granted in our daily lives, remains to be the final frontier for our thousands-years long technological journey. Once again, the creation set the boundaries for human development.

God willing, you are to be an expert hardware specialist or a good-quality programmer or a first-class network builder or a high-quality system administrator by now

But ever bear these important points in your mind: This Universe has such a Hardware Engineer who created all beings and the Earth as well; He made Sun a Power Source, Moon a System Clock. Such an Uninterrupted Power Source and such a System Clock that never goes astray and is never confused, so as to show the vast knowledge and the art of that Hardware Engineer.

This Person, at the same time, is such an Exalted Programmer who composed and assembled the gigantic Software called Life in the best way to operate on this vast globe, and has been operating it for millions of years; error-free, bug-free and devoid of any system crash. If you want to know how an Exalted Programmer He is, take a good look at yourself at the outset:

He saved your entire life code into one of your microscopic, infinitesimal cells, which you cannot see with naked eyes, and He too executes that code in that same minuscule cell of yours. Since it is obvious as clear as the daylight that the DNA is a program, and a program cannot exist without its Programmer, therefore your programming is like a mirror to that Exalted Persons Art of Programming.

Again, as he makes those cells communicate through innumerable protocols within your network which He made up of your entire cells, and since He also bestowed on you the essential hardware along with you to enable you to converse with another people in various languages and protocols, he also makes you see, talk and listen as before. And since, He prepared and enabled you to use various media such as light and sound, so that you can come to know about the things around you “ and you can discover and utilize those things, but you cannot add a new component “ hence there is such a Great Network Resource Person who knows what you need and gives your equipments as per your requirements. Your flair of networking is only a little piece bestowed on you by Him out of His infinite knowledge and a great blessing.

O my friend, do not be deceived! This beautiful World Life Software is just a trial version, as you can see; in any case you cannot save the properties and treasures that you hoarded so far. Therefore, know the Writer of this Beautiful Software of the Universe. Is it ever possible that a programmer to build up such a beautiful program, and never include an about file to introduce Himself? Therefore; see and learn the About files, which have been included by the Greatest Programmer, Hardware Expert, Network Professional and the System Administrator of this Universe, and work for acquiring the Full version of the Software. Do not forget, without skipping any of your actions, log files are being carefully saved in the background. These log files are going to be checked by that System Administrator, whose Power envelopes every being. O Man: If you are a Human, do not mix nature, coincidence, absurdity, and unbelief into these beautiful tasks; do not make it ugly, do not perform it ugly and do not be disgusting!
