The anecdote about the pink eraser isn't as impressive as the author makes out. A manual google search of 'why are erasers pink' returns the same article from Design*Sponge (that the author mentioned as the source for the response to his voice query) as the top Google result. So, the remarks about how the answer shows evidence of context awareness don't really ring true. The assistant is just passing his question into Google and reading back the response. The sum may be greater than the parts, but nothing revolutionary here.
