Teletype is old tech. Chat bots are old tech (though still improving). Mechanically moving keyboards that registers its own typing as a human user is old tech (word processors). This is just an artistic and nostalgic amalgamation of blending old tech with modern innovations. I was chatting with Eliza on a Macintosh LC in 1986. The only differences are that the keys don’t physically move when Eliza produces output and the chatbot is much more refined and versatile.
