That would certainly be an adequate definition for me
(possibly only getting 9 out of 10 in an exam,
since there are many Turing machines,
one of which might certainly output a given string
in a very short time).
But my complaint was really about the use of the words
"random", "entropy" and "white noise"
in what seemed to me a less than precise sense.
