So... in the actual book(s), the problem is a bit of both.

The 'science' goes wrong because... well, they do not have complete dinosaur genome sequences.

And they fill in the gaps with a lot of DNA from a certain kind of frog.

A frog, that is later discovered to change its sex, transform from female into male, in environments/situations that are not sufficiently male/female balanced.

The explanation as to why the dinosaurs will not be a problem is that they only make female ones, so the population will remain exactly as they engineer.

... this does not work, because some of the dinos transform their sex, and begin breeding, which they essentially entirely did not account for.

So... 'the science' absolutely fucked up there.

...

Also in the book(s)... Hammond is much, much more clearly an unscrupulous capitalist... think roughly somebody that would have their accounts managed by Patrick Bateman, or maybe like a modern techbro, but his tech isn't crypto or ai or hyperscaling whatever bs app... its genetic engineering.

(cough 23andMe cough)

The original movie makes him into... much more of a genuinely enthusiastic, but more innocently naive, and sympathetic character... he is much more straightforwardly a thinly veiled corpo asshole in the book.

...

So the books feature capitalism, capitalists, as another majorly bad thing that fucks up.

The idea as I see is that... these two things, when both unrestrained and pursued recklessly, well one of them would be bad enough on their own, but when you combine both of them, shit gets real bad, real fast, high likelihood of catastrophic co sequences.

Its the 'tech is not inherently good nor evil, it all depends on how a society uses it' line of thinking.

It just says hey, here's a worst case scenario for you to chew on, how seriously you should consider this.

Like maybe a modern version of this would be LLMs.

Theoretically, an LLM on its own, used reasonably, responsibly, can be a tool for arguably mostly good. You could theoretically power one of these things with wind, solar, geothermal, have a societal structure where its provided as a controlled and regulated public good, not a private for profit business.

But when you couple this with the ravenous nature of capitalism, well, a whole fuckton of shit starts cascading out of control into negative consequences... vital processes and info get fucked up by LLMs hallucinating shit and make heuristic decisions en masse that lead to say, millions of people being denied or charged out the ass for healthcare...

Major corporations massively downsize their work forces and replace them with 'good enough' (but not really, actually) LLMs... which then craters demand in a consumption based economy, so now we have a Great Depression 2.0...

And the widespread usage of these things to answer anyones questions and do everyone's home or coursework, means that now humans are net stupifying themselves, as they no longer need to learn how to do critical analysis, research and source verification, etc.

...

Its been a while since I've seen the original movie, fhe first sequel... and then yeah, never saw anything after that, because they just look immensely, increasingly stupid and nonsensical, not even having internal logic that is coherent or consistent... so I can't well comment on how the movie universe has evolved.
