For decades, Ray Kurzweil has been an unofficial spokesman for the transhumanist movement.

And in 2008, he said that humans would become infused with nanorobots, which would vastly improve the human body.

If you go out, even to 2045, that's only four decades from now,

most of our intelligence of our human civilization will be non-biological.

We're going to put this inside our bodies and brains.

So we're going to become machines, but not, and if you say that,

then people go, well, I want to become a machine,

because they're thinking of machines as we knew them from the 19th century, which were much

type of machine that's actually greater, more subtle, more supple, more intelligent, more creative,

more beautiful than humans.

In 2010, he interviewed Robert Freitas on the future of nanotechnology, who said that

nanorobots could cure aging and death.

Medical nanorobots really have the potential to extend human life more or less indefinitely.

So what's your view about the role of death and do we need death?

Death is something that is an end.

It's an end of life.

It's an end of progress.

It's an end of thoughts.

It's something to be cured.

Aging is a disease.

It's a curable disease. Nanomedicine is the cure for that disease. He said that this technology is expected to be deployed by 2020 and that laws will be in place to
