It criticises science for profit. They literally invite various scientists who know their stuff and they all tell Hammond he's a fucking idiot. It's much clearer in the books, though, where you get to read where they notice all the enclosure mistakes that were made by Hammond's team.
Jurassic Park is a satirical comedy about capitalism. Hammond spares every expense. The first scene is a man being killed on the job. He built the park in a country with cheap labour and low safety standards. He essentially had 3 people running the park. They bred raptors just because they could and he put his own grandkids (a metaphor for the future) in danger due to his own hubris and ego. They are literally man made monsters in an amusement park created by exploiting nature using untested technology. The metaphor for the dangers of greed could not be more on the nose, and I'm baffled it isn't more commonly understood.
My favorite part is when I have to take mandatory trainings on security and integrate automated scanners for vulnerable libraries, but none of our projects have funding to actually implement the basics, like encryption+authentication.
We have the mandatory security training at my company and they said it was going to be revised after a few of us showed how the advice it gave was insecure and incorrect!
In a bank we work for, there is a mandatory security training for employees, mandated by the parent supranational. The bank tried to correct the mistakes in the training or at least make the training optional, as the bank provides its own, more correct program. Rejected by the mother company, mandatory training is mandatory, even if it is wrong.
There's a linux port for the SGI file browser featured in the movie: https://fsv.sourceforge.net/ ---- haven't run it in ages, though; I don't know if it's still functional.
I think they did at one point, but during the plot he's the only one and he's working unpaid overtime, because he warned them when he signed his original contract that the system they wanted needed more engineers and more time but they didn't listen and then threatened him into working for free when the system wasn't ready at the end of his original contract. This is the direct reason why he committed the corporate espionage that caused the whole park to go fubar.
The counterpoint is that Nedry was hired to stand up infrastructure and is likely the one responsible for not properly staffing that effort. The CEO isn't going to know anything about that and will naturally defer to the people hired for those tasks. If Ned says it's all fine and he's coming in under budget, no reason to doubt him.
We all know lone wolf types which will hack together systems and pretend like everything is fine just so they'll never be bothered by the presence of others questioning their brilliance.
Hammond chose the cheapest contract bid for his computer system needs, choosing a contracting/consulting agency in Cambridge MA. Nedry worked for them and was responsible for fulfilling the contract. He complains about not getting paid enough personally and I doubt there was further room in the contract budget for more headcount.
Again, this was because Hammond went cheap on the contract. This is just one instance where he is repeatedly shown to be a cheapskate throughout the movie.
