Brain-computer cooperate to manipulate real world
Future computer will be fully integrated with human's brain as well as billions of daily objects such as simple as cups, table, window, paper etc. So when we intend to do something we just "do" it in our mind and certain objects will follow the command to complete whatever we pictured in head. Computer and cloud technology is so advanced that the execution ability of computer is way better than human's own hands, therefore you don't have to be a real painter to make a "masterpiece", all you need is bold imagination, the rest, leave it to computer.
Controversy: if all the work, art, craft were made by computer(thus every detail is optimized in the very standard and sophisticated way), could they still be called our own intellectual result? Are we giving away one of a few things that we human are so very proud of?
Actually it wouldn't be a problem at all. Despite the utilizing of computer, every creation is still based on our pure idea and imagination, our desire and need, you can't say that if we invented a better tool to write then what we write won't be count as original as before. Plus, as civilization reaching to a higher level it is inevitable that we will ditch some of the old methods and adopt new methods and thus achieve a newer competition on a higher level. When Da Vinci created Monna Lisa nobody was worried about the fate of caveman's drawing on stone walls. Same reason, it's not that we won't treasure all we treasure today, but new technology will open up a new horizon, new platform for us to practice our knowledge and wisdom.
Computer-brain to manipulate virtual reality
While computer and brain fully integrated into a ceaseless unit, it opened up possibilities in two opposite directions, one is real world, another is virtual reality world.
A gigantic, vivid, colorful virtual world or even multiple worlds will be designed and created for people to have virtual life in computer, this world can be private, can be shared, but in total the virtual world will for sure exceed the size and richness of our real world. By then a fantasy land, a heaven, even a hell can be existing. Criminals can be put in educational virtual reality world to train and clean their spirit, in extreme cases we could put the worst of worst people into a "virtual hell" to forever lock them away from the world.
All education can be done in virtual world, when you learn history, you can stand at the world war two battle field to witness historical events as if watching a movie(even participate in it in some degree to see what would outcome would be achieved if some certain factors were influenced in history).
Countless scenarios of how virtual reality can affect our life have already been anticipated and vividly illustrated in novels, movies, just think of Inception, Total Recall, Matrix, eXistenZ.... Indeed, you could live forever in VR world. Then there will be argument about how important these virtual reality lives really are, on moral, ethical and legal levels, they would be very challenging to our current society form. But the trend to a equal judgement will prevail, virtual world will gain a legitimate place in society, it will be morally and legally protected and respected, people can choose between these two kinds of life, or even live a double life. It's like we created an infinite parallel universe that we can visit anytime, there's always a portal right there, between two worlds, people choose left or right like choosing between two neighborhood, no need to argue which one is realer.
