Washing Machines, Lawn Mowers and the such like are all early forms of robots if you consider the word to mean a machine doing a task which was formally done by human beings or animals. Machines do not require holidays, lunch breaks or time off. Increasingly these machines are more reliable and suffer less 'time off work'.
In an increasingly sanitised and digitalised age, the interaction of trainer and animal in the sawdust circle provides something real and raw that no other form of entertainment can offer. Rather than demeaning animals, it impresses all ages with their skill and intelligence, and enhances our relationship with nature.
