SETI astronomer Seth Shostak is betting a cup of coffee that aliens will be found by 2036. By 2036 Shostak hopes that computers would have increased in speed and efficiency enough to have looked at about a million star systems. It’s his gut that says “a million is the right number to find something”.
Seth Shostak should not forget the role of The Square Kilometre Array (SKA) with its Cradle of Life project which will be “greatly expanding on the capabilities of projects like SETI” in all of this.
