Could you elaborate on that?
To me it seems that if you can solve riddles then you are fairly close
to making a computer that passes the Turing test. Especially if the
riddles are not of the same form: "What is ten plus hundred?" "Enter
the last five digits of my phone number" "Enter yesterday's date"
First of all you need to solve speech to text. Then you need to parse
and understand the sentence. Both problems have proven to be really
hard problems. Throwing a botnet after this is not going to solve it
if the algorithm is simply not there.
