Some other questions touched on the subject of Mike's absence near the end of the book. My question relates to the sudden absence in relation to Prof's death.

Here's why I think this:

* Prof dies, Mike goes silent. This happens within just a few pages of each other.
* Prof proves he's a genius puppet master during the whole book - to a large degree manipulating both Earth's and Luna's governments as well as his fellow revolutionists.
* Prof and Manuel have a strong bond with each other, not unlike the relationship between Manuel and Mike.

Did Mike really have an awesome AI or was he just another of Prof's tools like Manny and Wyoh were?
