This is so good.
This is peak science fiction, a work that uses the lens of the future to talk about contemporary societal/technological issues just as much as it talks about bigger picture ideas such as the human condition.
And oh, does Terminal/Shell_ do a good job at that. The conversation between the two leads alternates between character study and "The Measure of a Man" debate about what qualifies as human. And once we get a view into the rather opaque feelings of the programmer...
The attention to detail with scripting is also very appreciated-- the back and forth between user and program in the first act really added to the charm just as much as Polyco's cute expressions.
