What happens?
I’m not sure I understand the desire to control computers with conversational language. Computers are a collection of on off switches. I personally would much prefer being able to control exactly which on off switches to switch, instead of just telling the black box to do something and for it to make no mistakes. It just doesn’t strike me as a good idea to give the incomprehensible matrix weight the ability to make decisions about what to do on my machine. There’s just far too much ambiguity for my comfort here.
