You can't just drop compatibility. We will have A.I. trained voice systems that mimic natural speech just enough to be understood by duplex while compressing the exchange to a minimum. Data transfer will be measured in microwords per second. Future versions of duplex will of course detect this kind of compressed speech and reply in kind, falling back to normal speech only if the immediate response is similar to north american confusion.
