1. I do not think all the pointing, pushing and pinching with the fingers is going to last very long as a way to manipulate a computer screen. I mean the advancement between a touch screen and something that you do not touch but still have to go through the physical motions is not that significant. Both involve tracking the physical movement of the user. What I believe is coming very soon is advanced eye movement technology coupled with facial movements and micro expressions. This will quickly replace all the finger pointing and flailing arms. Even though the eye tracking and facial technology reading switch will be a far superior method of computer interaction than the current finger pointing method, it to will be short lived and replaced by brain scanning technology. All the things learned from the eye and facial tech will literally open the door to reliable brain wave technology the very moment the eye and facial tech is perfected. I'm not referring to the already available goofy looking apparatus you see worn on people's heads with the wires and antenna used to control a small drone after lots of practice. I'm talking about a reliable system that reads brain wave activity, filters out what is relevant and do it all when the operator is from five to ten feet away from the computer. The brain scanning technology will employee highly sensitive receptors that detect a users specific brain waves that indicate a desire to move this or that on a computer screen and then make those moves. In the beginning a brief training/learning period in which eye scanning technology and brain wave scanning technology will work in tandem until the brain wave tech is perfected. To use the technology all a user need do is address the computer and then literally think of what pages to open and think which selections desired. When perfected even someone completely blind could use any computer. Side Note: No more passwords. The computer will automatically open, turn on, allow access, etc by simply recognizing your unique brain wave patterns. Even better than than using finger prints. In high security applications where you must use something like a password to gain access, that password would instead be a memory that only that user has. For instance a man needs a password setup or let's call it a memory verification. He instructs the computer to label this next thought to be his password, similar to how we now have to type a password in twice to set it our computers. He then thinks of the day that just he and his dog explored a newly discovered hiking trail. Unless the computer receives those memories of that experience, right down to how it made him feel and even in that memory how he perceived his dog as either happy or cautious, will be part of the unique password that cannot duplicated by anyone else. Even if another person knows the memory and even knows the feelings associated with it there is enough subtle differences to prevent access. Eventually even the brain wave scanning tech will become obsolete, probably sooner than later, as the inevitable convergence of man and computer are realized. Within our own bodies we will have tiny rice grain sized computers implanted that are many hundreds of times more powerful than any laptop or desk top computer that currently exists today. With the aid of nano-technology the tiny computers will be linked to our brains by ways yet invented making it possible to simply think about something. Once thought, all the data in the computer would become available and searchable just like our own memories. As an over simplified example imagine that a man breaks something in his home and then decides to repair it. Initially he will attempt to access any knowledge he may have in his own brain of how to repair the broken thing. But, If his own brain lacks the sufficient knowledge the computer will then make available all the information it has concerning fixing the broken thing. Also the computer will link information about fixing something else that requires a similar or exact procedure, just as our minds relate previously learned useful information about one thing and apply that information to something different but similar. No more having to type a request into a computer exactly one particular way to obtain desired information. When accessing his implanted computer the man will know the difference between the computer supplying the information and his mind having the information, even though the information from the computer will be interpreted by the brain much like his own thoughts. Additionally microscopic connections from the computer to the mans optic nerves will enable him to see examples much like the way that we view a computer screen today. The order and process of the human brain interacting with the implanted computer will be in such a way that the human brain learns what the computer has just supplied. So the next time the man breaks the thing it will be his mind that is first in searching for repair information then when the mind realizes it has insufficient knowledge it turns to the computer for instructions to make the repair. But the second time the thing is broken, having already done it before and the brain remembering the steps, input from the computer will not be necessary unless the mind desires to compare and refresh the memory. It has to be this way in order to keep our minds from becoming nothing more than a mouthpiece to the computer requesting information with out actually having any of its own nor learning the procedure. A fail safe mechanism designed to keep the human mind engaged, learning and not becoming dependent. Some day the internal computers in the human body will be connected to the brain, spine and nerves of the muscles. This would enable a man to almost instantly access what is known as 'muscle memory' in a situation that requires fast movement of the body or specific parts. An example would be a man finding himself in a dark ally about to be attacked by three attackers. Though the man has never had a self defense class in his life, the computer, almost instantly, supplies the man's brain with the knowledge of thousands of hand to hand fighting experts along with the learned physical dexterity. In a manner of a second the man will function physically as if he has practiced self defense techniques all his like. In essence he will have the experience and not just the how to data. In the construction equipment business I used to say that there is a huge difference between a man who knows the functions of a backhoe and man who has used a backhoe for twenty years. Another example would be someone who knows an artist uses many colored paints, an easel, a brush and a canvas to create art but doesn't know how to paint. Where is an artist knows that he needs paint, an easel, brush and canvas along with the knowledge that years of perfecting his painting skills has given him. With the integrated knowledge and experience a man could pick up a Stradivarius violin and within 1 to 2 seconds play it as if he was born playing it. The possibilities are as endless as the imagination.
    Another prediction in the not so far future will be the integration of man and mechanical enhancement. We already have some outstanding exoskeleton prototypes that can turn an average man into a man with super power and near endless endurance. An integrated computer in a man with an exoskeleton would be something so awesome that nothing in our history has even come close to comparing with except that which is found in fairy tales and comic books. But the ultimate, and I believe the inevitable, achievement of man will be the near complete replacement of mans body with that of an enhanced far superior mechanical body with an integrated micro super computer all coupled seamlessly together with the human brain. A mechanical body, easily repairable, with strength and endurance of a thousand men is coming. A mechanical body capable of enhanced sensation again a thousand times greater than a normal man. Then that super body all controlled by a human mind integrated with a super computer would be absolutely fantastic and I want to be the first to be re-fitted and upgraded.
