As the original Jurassic Park showed, it’s always helpful to have a couple of children around during your dinosaur rampage, should you happen to run across any Unix systems. Children, after all, know this and other things that only the young and hip can understand—like the influx of dinosaurs into new neighborhoods that leads to a Jurassic World, and all the small-batch carnage that follows. Hence the addition of Ty Simpkins, last seen irritating Robert Downey Jr. in Iron Man 3, possibly next to be seen asking needling questions of genetically engineered dinosaurs, until they realize that maybe they should have stayed back in Jurassic Park, seeing as Jurassic World is all overrun with people’s annoyingly precocious kids now.
