Eliza is fun but the fun is coming from your own imagination.
When you get tired of the repetition, then if you are coder you look into how you can update the script.
When I did that, I found some amazing ideas in the code. Like mapping one cue word or phrase to many possible responses.
Do you pick them randomly or cycle through list?
Another thing was Eliza mirroring back to you what you just said, simply by exchanging I for you and vice versa. Also it picks up words after a key and plugs those into a preset response. Cheap trick but gives the feeling the code understood what you said.
Eliza only remembers the last thing you said, imagine what might be with more memory?
Like sessions saved and responses custom tailored to person's history say by picking up patterns, often used words or phrases.
