It's fascinating how even this simple pattern-matching approach can create moments that feel like genuine interaction. The converastion has that classic ELIZA feel — never quite answering directly, always turning things back to the user, and occasionally hitting on somthing that feels surprisingly insightful!

Smalltalk (Pharo) implementation of ELIZA, an early natural language processing computer program created from 1964 to 1966 at the MIT Artificial Intelligence Laboratory by Joseph Weizenbaum.
This implementation is based on this Python implementation and elizabot.js (for the welcome messages). There are similar implementations for Go and Swift.
- Pharo 10 reference platform.
- Examples and tests included.
