They 'anticipate every need' if all your needs revolve around turning on things according to a schedule, or at most according to where you are physically.

For me, turning on lights etc are such a small part of my day, not to mention my 'needs' as to be completely insignificant.

If the machines would do something like sort, wash and fold the laundry that would be something, but as it is I people just buy them for novelty value.
