"It is not clear that Kanzi can do all aspects of making, controlling and employing fire at this point in time. For example he doesn't stay close and carefully monitor the fire once it is going, though he will throw on wood at a distance. But he has not had the true environmental pressures on him that would lead him to desire to use fires for warmth. He has a warm bed every night so he doesn't need to keep himself warm, like the humans who first harnessed fire did, and he has never encountered predators, so he doesn't need to frighten any away. If these were employed in the future, his fire-making skills might leap into the action at a much higher level. He doesn't need to sit around a fire at night, as early humans did. He heads to the safety of the concrete buildings that make up the facility. But what if they he had no such shelter? Would he want to keep their fire going to keep predators away and stay warm at night? For now, for Kanzi, fire is about making cooked food, which he enjoys very much."
