Schopenhauer would say that Alexa does in fact have will to turn the lights off. A burning will, the same will within yourself and everything that is not idea. That it is your word that sets off an irreversible causal sequence of events leading to the turning off of the lights. Schopenhauer would ascribe his “Principle of Sufficient Reason” as the reason for happening. It is not that Alexa chooses to obey, but by the causal chain enforced by physics and more leaves the will of the universe no choice but to turn off the lights. Same reason why the ball eventually falls down when thrown up. I believe this is the metaphor Schopenhauer uses in his World as Will and Idea.
However I have to make one remark.
