Just what device did Turing actually INVENT? Oh that's right NOTHING. Just a piece of paper with some questions on it...

Turing replaced Godel's universal arithmetic-based formal language with what are now called Turing machines. He proved that some such machine would be capable of performing any conceivable mathematical problem if it were representable as an algorithm. Without those ideas nobody would have been able to build the modern computers that we currently use. Did he build it with his own hands - no. Did he make it possible to build them - yes.

It also contained some bogus predictions, such as Turing's claim that computers would be generally accepted as thinking by around the year 2000

Predictions for 50 years out shouldn't be the judge of genius.

Turing was a pseudo-scientific lunatic. Let's see what the crackpot actually wrote:

"I assume that the reader is familiar with the idea of extra-sensory perception, and the meaning of the four items of it, viz. telepathy, clairvoyance, precognition and psycho-kinesis. These disturbing phenomena seem to deny all our usual scientific ideas. How we should like to discredit them! Unfortunately the statistical evidence, at least for telepathy, is overwhelming." --COMPUTING MACHINERY AND INTELLIGENCE, BY A.M.TURING
