The world done and got sick on us... (in oh so many ways...).
In the words of River Song, spoilers:
I may have said this in my review (can't be arsed to go and look!) but I found all the Hitch-Hikers references a massive distraction and, as you say, unrealistic. Someone would have thrown the copyright hammer at the company for such flagrant commercial use of the IP, if nothing else! If the company had to be a bit geeky, he could have gone with names of computer pioneers, like Babbage, Lovelace and Turing etc.
Although I enjoyed it, I think with distance I would mark False Values down as well, and give it 4/5 (though that might go up again on a re-read!).
At the end of Lies Sleeping it felt like there was going to be a massive change in direction for the series, but that never really happened. False Values feels like a side story before what comes next, although I think there may be parts of it that will prove to be very significant later...
