These comparisons are often not terribly accurate. Every year thousands of sailors travel under the oceans in military submarines, thousands of commercial divers work on pipelines, cables and oil rigs, thousands of hobbyists engage in recreational diving, and hundreds of researchers travel to great depths in the interests of science. Robots regularly venture where humans do not. What is usually fueling these claims is jealousy, or more politely, professional envy: the United States spends billions of dollars exploring space every year, and far less money exploring beneath the sea.Continue reading...
