An email, even if it goes to a mailing list, differs from a public web
page by being addressed. A video conferencing session differs from a video at
some home page by being addressed. Machines, including chatbots, can read and
write e-mail, but they might be too dumb to qualify as entities. A really
capable AI based chatbot that passes the Turing test without mimicking a
mentally disabled or dumb person is an entity.
