I don't see a need for pessimism there. If speech is text plus prosody, then I see adding a prosodic channel to the programming interface as augmenting/enriching programming languages, not replacing them. I also don't think speech is 'special' in terms of intelligence (e.g. Deaf people are just as intelligent), so enriching text could just as easily come in a different form of imagery (prosody being a form of mental imagery) such as drawing. And that is the area that Victor is working in.
