No. If something has evolved it is always present in the genes and it is easier for it to emerge again later.

Quote: This is actually kind of a scary thought for me because humans of course are evolving. Imagine that if in the near future we create machine minds which are intellectually superior to us. Suppose those minds are benevolent to us and take care of us. If our own intelligence is no longer contributing to our fitness we may loose it. A million years from now, our descendants might be as intelligent as cows.
What do you mean "a million years from now"?
Go chew that cud boy.
You can fix ignorance, you can't fix stupid.
