Is SETI Barking up the Wrong Tree?

Seth Shostak writes on Space.com:

It’s been 46 years since Frank Drake aimed an antenna at the stars in the first modern SETI experiment. His hope was to hear a deliberate signal – guided into space by intelligent beings – rather than the natural, noisy dance of hot electrons.

Since then, SETI has expanded its search space, bettered its equipment, and refined its strategies. But the bottom line hasn’t budged: still no confirmed chitter from the cosmos.

Some people mistakenly confuse a long search with a thorough one, and figure that the lack of a SETI detection indicates that we’re alone in the Galaxy. This, however, is nonsense.
