An MBA, an engineer and a quantum computing physicist check into a hotel. Middle of the night, a small fire starts up on their floor. The MBA wakes up, sees the fire, sees a fire extinguisher in the corner of the room, empties the fire extinguisher to put out the fire, then goes back to sleep. The engineer wakes up, sees the fire, sees the fire extinguisher, estimates the extent of the fire, determines the exact amount of foam required to put it out including a reasonable tolerance, and dispenses exactly that amount to put out the fire, and then satisified that there is enough left in case of another fire, goes back to sleep. The quantum computing physicist wakes up, sees the fire, observes the fire extinguisher, determines that there is a viable path to practical fire extinguishment, and goes back to sleep.
