From Richard Crews
Learning to talk to dolphins is a charming, romantic notion, but it seems a big jump from the researchers using their software to analyse footage of sign-language and gym routines (7 May, p 23). Unnecessarily big.
Wouldn’t it have made more sense to try it with some obscure human languages first? The investigators and their software might learn things that would then be useful in inter-species communication.
