Do you think a smart device will one day be able to have a conversation with someone in ASL? What could this be used for?

Yes of course. We already have devices that can read facial expressions and respond to them. At some point technology will evolve to the point that it will understand hand signs as well. It can be used to support a conversation with someone who is hard of hearing, or teach people how to sign in ASL without an actual teacher.
