The failed dreams of early machine translation researchers are not merely historical curiosities, but illustrations of how intellectual biases can marginalize pragmatic solutions, in this case a human-machine partnership for translation.

In this article, we first recount that history. Then we summarize the recent breakthroughs in translation made possible by a healthy AI-HCI collaboration.
