Currently Google responds to our typed query, soon we can sit behind our tv and ask ‘health’. And after that ‘When was that guy talking about health?’ And even later it’ll search for all kinds of synonyms. It goes on and on. Not just for Google, but for all brands. We’ll be able to ask such questions of all brands. Like it’s always been the most normal thing on the planet. For now we’re very busy with reaction properly to the clicking and typing of our customers, but in the meantime technology is a few steps ahead of us.
