Turing test Kurzweil (optimist) about whether a computer will pass a lengthy Turing test by the year 2029. During the Long Now Turing Test, each of three Turing test judges will conduct online interviews of each of the four Turing test candidates (i.e., the computer and the three Turing test human foils) for two hours each for a total of eight hours of interviews. The bet specifies the conditions in some detail. 1990 marked the fortieth anniversary of the first publication of Turing's "Computing Machinery and Intelligence" paper, and, saw renewed interest in the test. Two significant events occurred in that year:
Turing completeness data is called a Turing oracle. Even a Turing oracle with random data is not computable (with probability 1), since there are only countably many computations but uncountably many oracles. So a computer with a random Turing oracle can compute things that a Turing machine cannot. All known laws of physics have consequences that are computable by a series of approximations on a digital computer. A hypothesis called digital physics states that this is no accident, because the universe itself is computable on a universal Turing machine. This would imply that no computer more powerful than a universal Turing machine
