Engines of Construction 111

Protein engineering represents the first major step toward a more general capability for molecular engineering which would allow us to structure matter atom by atom. Director of Exploratory Research Genex Corporation COAL AND DIAMONDS, sand and computer chips, cancer and healthy tissue throughout history, variations in the arrangement of atoms have distinguished the cheap from the cherished, the diseased from the healthy. Arranged one way, atoms make up soil, air, and water arranged another,...

Growth on Earth does face limits since Earth has limited room whether for farming or anything else

Not fundamentally he was wrong chiefly about timing and details. Growth on Earth does face limits, since Earth has limited room, whether for farming or anything else. Malthus failed to predict when limits would pinch us chiefly because he failed to anticipate breakthroughs in farm equipment, crop genetics, and fertilizers. Some people now note that exponential growth will overrun the fixed stock of Earth's resources 16 , a simpler argument than the one Malthus made. Though space technology will...

The Limits to Growth

The chess board is the worid, the pieces are the phenomena of the universe, the ruies of the game are what we caii the iaws of nature. IN THE LAST CENTURY we have developed aircraft, spacecraft, nuclear power, and computers. In the next we will develop assemblers, replicators, automated engineering, cheap spaceflight, cell repair machines, and much more. This series of breakthroughs may suggest that the technology race will advance without limit. In this view, we will break through all...
