Computer scientists: "Let's discuss if this system can solve any computable problem!" Me, a practical developer: "Cool theory bro, but can it run Doom?" The "Can it run Doom?" test has become the unofficial benchmark for computing devices since the 90s. Forget your fancy theoretical computer science - if your toaster, calculator, or pregnancy test can run a demon-slaying game from 1993, that's when you've truly made it in tech.
