Writing well takes active thought. That's why this quote is, to me, giggle worthy:
>"In 15 years I think the input interface and the idea of a 'document' [will] be entirely reimagined," Chen suggests. "I don't think we'll be at telepathy in that timeframe but I can see a lot more speech and audio playing a larger role for input. Video is already augmenting the document, but VR could be ubiquitous by then."
Formal writing style - especially in long essays - is quite different than spoken word cadences. Basically my point is people don't customarily speak with the same discipline or rigor that they might put into writing. Tack on the issue, in the US at least, of thick regional accents and I really, really don't see Voice Input being the amazing game changer it can be advertised as from time to time (see: Siri).
