Get Smarter
byJamais Cascio
Pandemics. Global warming. Food shortages. No more fossil fuels. What are humans to do? The same thing the species has done before: evolve to meet the challenge. But this time we don’t have to rely on natural evolution to make us smart enough to survive. We can do it ourselves, right now, by harnessing technology and pharmacology to boost our intelligence. Is Google actually making us smarter?
Seventy-four thousand years ago, humanity nearly went extinct. A super-volcano at what’s now Lake Toba, in Sumatra, erupted with a strength more than a thousand times that of Mount St. Helens in 1980. Some 800 cubic kilometers of ash filled the skies of the Northern Hemisphere, lowering global temperatures and pushing a climate already on the verge of an ice age over the edge. Some scientists speculate that as the Earth went into a deep freeze, the population of Homo sapiens may have dropped to as low as a few thousand families.
The Mount Toba incident, although unprecedented in magnitude, was part of a broad pattern. For a period of 2 million years, ending with the last ice age around 10,000 B.C., the Earth experienced a series of convulsive glacial events. This rapid-fire climate change meant that humans couldn’t rely on consistent patterns to know which animals to hunt, which plants to gather, or even which predators might be waiting around the corner.
How did we cope? By getting smarter.
