Inputting code with voice is generally difficult, often due to variable names, casing, punctuation etc being hard to get right in voice-to-text. I think this might help quite a lot with that.
_However_, some of the hardest things in voice coding isn't necessarily just the input. Navigating large codebases is hard, and particularly editing existing code can be extremely difficult, probably much more difficult than just inputting new code.
I have my doubt that with the demonstration shown here, that it's able to make complex editing tasks simple, but if it does - I cannot overstate how huge of a leap forward it is.
