Michio Kaku: Mental communication and infinite knowledge are on the horizon


Eventually, a computer chip will cost a penny,
which is the cost of scrap paper. They’ll be everywhere and nowhere, including
your eyeball, in your contact lens. You’ll blink, and you’ll be online. And who are the first people to buy internet
contact lenses? College students, taking final examinations. They will blink and see all the answers to
my exam right there in their contact lens. And this can be very useful, if you’re at
a cocktail party, and there’s some very important people there that could influence your future. But you don’t know who they are. In the future, you’ll know exactly who to
suck up to at any cocktail party. On a blind date, they could be great. Because, of course, your blind date could
say that he’s single, he’s rich, and he’s successful. But your contact lens says that he pays child
support, that he’s three times divorced, and the guy is a total loser. So yes, we’re going to have almost infinite
knowledge. And then beyond that, we will communicate
mentally. That is, we’ll be able to think about emails,
think about images, memories, and send them on the internet. Already, we can record memories. This was done two years ago at Wake Forest
University and also in Los Angeles. We’ve been able to record small memory, short
memories, in mice. Now it’s being done on monkeys. Next, Alzheimer’s patients, they’ll push a
button, and memories will come flooding into their hippocampus. And maybe one day, you’ll push a button and
have that vacation that you’ve never had. So we’re entering a new era, where the internet
itself could become brain net. Brain net could replace digital internet. Instead of zeros and ones, you’ll send emotions,
feelings, memories, on the internet. And of course, teenagers will love it. Instead of putting a happy face at the end
of every sentence, they’ll put the entire emotion– their first dance, their first date,
their first kiss, right there on the internet. And that’s going to revolutionize entertainment. Because remember the talkies? When the talkies came, the silent movies went
out of business. No one wanted to see Charlie Chaplin when
you could hear actors talk. So movies are nothing but sound and a screen. Think of what will happen when you can feel
emotions, sensations, feel what the actor is feeling. Then the movies will seem so barbaric. They’ll seem such like a dinosaur technology,
once we have brain net capable of sending emotions, feelings, on the internet.
