This one is just pure stupidity. Border Control and Customs announces the exemption one day, Trump immediately walks it back the next, all while markets are still closed. A bunch of idiots probably bought options on Apple and are going to get absolutely screwed when markets open today. If I had to guess the exemption was planned and got out too early somehow.
A more complicated but ultimately faster approach is using a structure like an Entity Component System. You build an entity (deer, person, plant) out of components that are just data (health, hunger, mood), and then each type of component has a corresponding system that updates all the components at once based on other values. It’s somewhat similar, but you save space on unnecessary components not being added, and it packs the data together in way that is faster for the computer to iterate through.
It’s the same kind of rhetoric they use against gun control. It’s always a mental health problem, but they won’t address that either because they prefer mentally ill people to suffer.
