Definitely still early days - interestingly one of my animal behaviour profs back in the day reckoned that once we can read animal thoughts we may not find what they have to 'say' all that interesting. As someone who studies behaviour for a living, seeing them do the same exact things day after day, I think she may have a point. But I reckon we're in for some surprises with the likes of dolphins and Cephalopods though :)
