The World Without Computers

Eventually, computers will be obsolete. Not in the general sense of the word, but personal computers specifically.

What is the point of a personal computer?

I use mine to write papers, make presentations or websites (and blog posts like this one), and to check email. You can also use computers to advertise and sell products and services (e-commerce).

So, yes, computers are useful, especially as a means of communication and business, but isn't there better?

Email & Communication: What if your mind stored a mental image of everyone in the world, even people you've never met before, and you could use thoughts and/or gestures to browse or search these mental images of people to find the one(s) who you want to communicate with. Then, you could think of the communication you'd like to send and it would effortlessly manifest before you while you're thinking. After sending it, the person would get your message upon checking his mental inbox. Spamming would be easily traceable and regulated.

Search: Why would I need a PC to find what I'm looking for when I can tap into the collective knowledge of all human beings for free by merely snapping my right thumb and middle finger together.

Business: Business and money will soon be obsolete once we have robots doing all of our work for us. We won't have to pay robots to make or do anything for us. Instead of hefting over $20 for a nice dinner, we can tell our robot "sudo make me a sandwich" or merely think it or make a gesture and it will do just that with exactly what you want. Plus, all the food will be grown locally in your backyard garden (managed completely by your robots). And it will be completely organic and everyone will only eat whole plants because that is the healthiest way to eat. Read The China Study if you don't believe me.

And we certainly wont need planes when we can instantly teleport to one of the hundreds of millions of galaxies.

With all these technical advancements and gadgets, will humans be happy? Or will depression rates be even higher?
When will humans really learn to enjoy life to the fullest?
