We'll be able to have very intelligent, little robots with computers going inside our bloodstream, keeping us healthy from inside, destroying cancer at the level of one cell.

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

Biological evolution is too slow for the human species. Over the next few decades, it's going to be left in the dust.

There are downsides to every technology. Fire kept us warm, but also burned down our villages.

My view is that consciousness, the seat of "personalness," is the ultimate reality, and is also scientifically impenetrable. In other words, there is no scientific test one can postulate that would definitively prove its existence in another entity. We assume that other biological human persons, at least those who are at least acting conscious, are indeed conscious. But this too is an assumption, and this shared human consensus breaks down when we go beyond human experience (e.g., the debate on animal consciousness, and by extension animal rights).

In 1999, I said that in about a decade we would see technologies such as self-driving cars and mobile phones that could answer your questions, and people criticized these predictions as unrealistic.

Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity -- technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.
