  This is a theme which is explored in several different ways in the book. Another commenter has already related the tale of the man who ran an automatic optimizer on a copy of his own program. The optimizer noticed that the copy of the program had no inputs and no outputs, so it optimized it to an empty program. The man was understandably dissatisfied, because the empty program has no subjective experiences, while the man does. You might say that he made the mistake of optimizing a program with no inputs or outputs, but he would say that the designer of the optimizer made the mistake of not considering the subjective experience of the software to be valuable. It's certainly true that you can have a worthwhile life even if you stop talking to other people. At the very least, there have been hermits who have thought that they were having a worthwhile life, and who are we to argue? The author of the brief "explanation" errs, I think, in simply using the phrase "computation is […] subjective". He should have instead said that sapient computations have a subjective experience. But if you don't believe that minds are software running on a funny kind of Turing machine, then even that statement might be nonsense.
