Doing what's ethically right rarely means taking the most convenient path. Fridges and pantries take a considerable amount of space in our homes. These could become part of an automated storage system.
My point is that a generalist-humanoid robot can be used for nefarious purposes more easily than a specialised robot like a Roomba. A humanoid robot could, in an extreme case, perform a civil arrest or prevent you from leaving your house until the police arrives.
Ultimately it's our decision to make.
1. Do we want to be governed by machines?
2. Do we want to relinquish our freedoms to the whims of corporations?
