SS,
Yes I agree with you. I sometimes try considering whether I would prefer a mobile robot / android or simply an "Intelligent House" that would monitor comings and goings, heat/cool, occupant locations, music & various media, weather, finance (bill paying, etc.), News, sports (for those that like sports), security and more.
Perhaps a combination of both.
We already have smart homes and practically anyone with any budget can get started in the field / hobby and add to it as time and money permit. The hurdle is FULL HOUSE Voice command / recognition. At present there are too many false echoes within a home that often lead to distortion, feedback through the electronics and other considerations. One day it will all come together!
