Which excerpts from "Household Robots Are Here, but Where Are They Going?" best cite textual evidence to support the central idea that robots will use machine learning to enable them to have meaningful contact with humans?

Select all that apply.

A. Matuszek says there is "a lot of value" in thinking of robots as companions, mainly for specialized purposes such as caring for elderly or isolated people, or autistic kids.

B. You don't need your robot to be humanoid to tell it to turn off the downstairs light (which Echo will soon be able to do) or order more detergent (which Amazon will gladly sell you).

C. During an interview, Jibo's product manager, Matt Revis, refers to Jibo as "he" throughout. "When you're talking to him," Revis says, "you feel like you're interacting with someone."

D. If teaching kids how to play the piano is the goal, maybe the humanoid approach is best. But if you just want a hub for your smart home, Echo's approach is better.
