The main problem with solar on the Earth's surface is that it is so intermittent, and we don't have decent storage yet.

The technology of synthetic biology is currently accelerating at four times the rate of Moore's Law. It's been doing that since 2005, and it's likely to continue.

Likewise, with solar, especially here in California, we're discovering that the 80 solar farm schemes that are going forward want to basically bulldoze 1,000 sq. mi. of southern California desert. Well, as an environmentalist, we would rather that didn't happen.

Information wants to be free, because the cost of getting it out is getting lower and lower all the time.

Over the next ten years, I predict, the mainstream of the environmental movement will reverse its opinion and activism in four major areas: population growth, urbaninzation, genetically engineered organisms, and nuclear power.

Do what's good for humans, modeled on how humans already do things; ignore what's convenient for computers.

The urgent finds you; you have to find the important. Importance is not fast. It is slow. It is not superficial. It is deep. And as a result, it's extremely powerful. When important matters go wrong, they undermine everything. When they go right, they sustain everything.
