Robots and AI
While true AI has yet to be created, many of the most advanced robots can convincingly mimic human speech patterns and behavior. It is, however, all smoke and mirrors, as these robots lack the capability to think independently. They cannot create anything new, and can only follow the directions of their programming.
Of course, the vast majority of the robots in New Edo are not nearly as advanced. Many robots are available for utilitarian uses, such as carrying objects or acting as intelligent surveillance cameras. Most robot design favors humans and animals, as anything else tends to make people squeamish.
