The voice interface experience(in general) so far is like trying to make a really stupid person do something for you. Out of context misunderstandings are the worst because it breaks your flow trying to understand why that happens and how to fix it.

I imagine that voice to code would be like standing over the shoulders of a junior coder who knows the syntax and some techniques just enough to follow orders but has no idea whats doing and when gets it wrong will be very wrong.
