Things I've considered automating: different light settings (temperature, which light to keep on, watch-style notifications/interactions when not at my device (usually because it's charging), instructions to nearby screens or audio systems, reminders... A lot of it relates to integrations and interactions which require too many button pushes. Voice control is one step closer to "mind-reading"-like experiences and having knowledge of who is in which room would improve the context-awareness of existing apps and whole-home systems. For example, ideally if I said "play some music" it would know who I was and what I liked vs others in the house. This is more than voice control, and is likely phone- or app-integrated, but every small step gets us closer. ;-)
