Ray Kurzweil

"By 2029, computers will have emotional intelligence and be convincing as people."

"By the time we get to the 2040s, we'll be able to multiply human intelligence a billionfold. That will be a profound change that's singular in nature. Computers are going to keep getting smaller and smaller. Ultimately, they will go inside our bodies and brains and make us healthier, make us smarter."

"Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it."

"I'm working on artificial intelligence. Actually, natural language understanding, which is to get computers to understand the meaning of documents."

"If you write a blog post, you've got something to say; you're not just creating words and synonyms. We'd like the computers to actually pick up on that semantic meaning."

"Sometimes people talk about conflict between humans and machines, and you can see that in a lot of science fiction. But the machines we're creating are not some invasion from Mars. We create these tools to expand our own reach."

"Supercomputers will achieve one human brain capacity by 2010, and personal computers will do so by about 2020."
