Sometimes Stock seems to be saying the same thing over again - parent pressure will make GCT happen - rather than trying to go more deeply into the arguments for and against. Overall, however, the book provides an interesting account of the benefits, such as longer life or higher IQ, which GCT might bring, together with a look at the technologies which might make it happen - for instance an artificial chromosome, which could be removed or upgraded when the bearers decide to have children of their own. It's a book which will interest anyone concerned with the future of our species, and certainly it shows that those who think that GCT should be banned are going to have to come up with some much more persuasive arguments."; include "amazinf.php"; ?>
