> McDonald's wants a machine that's so brain-dead simple to use safely and keep sanitarily that even a new-hire with 5 minutes of training can operate it effectively. They get that by forcing standardization on one unit and one vendor, and software safety mechanisms that provide a firm no-go when something isn't right. That doesn't really jibe with the article: "The machine overheats if it’s used too much within a certain time period. This results in mushy goop coming out or the machine shutting down and refusing to work until it resets and cools down," Shahram Mokhtari, iFixit’s lead teardown tech, said in iFixit’s teardown. Gonna go out on limb and rankly speculate that for health critical systems it's not advisable to assume that OUTPUT_GOOP || FAILSAFE is functionally equivalent to FAILSAFE.
