&gt; <i>People also forget that vocal communication is &quot;imprecise and slow&quot;. Even with the most powerful AI on the planet--other humans.</i><p>This.<p>It drives me nuts that some people still think a voice recognition interface -- even if that&#x27;s at all possible in the more general case -- is necessarily the best UI. Or gestures. Look, in a lot of cases I wouldn&#x27;t <i>want</i> to have a person listening to me while I explain what I want done as I wave frantically. Humans are notoriously bad at understanding some sorts of instructions. Why would I want to introduce this ambiguity to my computer?
