All these complaints and no one mentions "1 to the 4th power"?
For me the best part of the episode - Cogley's speech that ends act 3 (or is it 2?), about the injustice of Kirk not being able to confront his machine accuser - is surely relevant today in a way not seen in 1966.
I also love that Cogley is a book collector, that he perceives the law in books as somehow more real than what his descendant-of-LEXIS terminal can offer. In 1966 it took some amount of prescience (or at least an acquaintance with written SF that touched on the idea) to imagine a time when printed books would be scarce, and moreover that someone who cherished them would be considered eccentric.
