# Computation > Pretty important for a computer mod ## JNI We need the JNI system so we can salvage our hard labor thrown into NeoNucleus. Also because it is a capable engine and has a good API for architectures, and NCL is very capable. ## Worker threads Computers need worker threads for running non-synchronized code, because otherwise we're cooked ## Entities as machines Aside from blocks like cases and robots, we should also support entities like drones. Not only for OC parity, but also as addons would def love that.
