I remember the novel putting a lot of emphasis on how Hammond was a charlatan grifter and would lie about what could be done with genetic engineering (including his lies to raise money when starting the company). There's even doubt about exactly how much the park's animals really were resurrected dinosaurs.

It's a compelling modern retelling of The Island of Dr Moreau, but with believable science, and using chaos theory to argue why disaster is inevitable in the unstable system Hammond set up (rather than a mere "he was playing god"). I think it's a cautionary tale of science and engineering without morals. Cutting corners leads to bad science, and there are too many examples of bad science being actively harmful to society. If someone does immoral corner cutting, then who knows what is the depths of their fabrications?
