This would solve so many problems. Sometimes I like to think a bit about what level to set the lights at, but by that time the machine thinks I'm done with my request.
We need richer interaction models, and this is an area where it'd be nice if we could focus on programmers first to find the appropriate mechanisms.
I think modal systems that set contexts would also be amazing.
"Robot, let's adjust the lights"
Which could set the system into dealing only with lighting-related requests.
