Jaquet-Droz's Writer (1770s) is a mechanical automaton with 6,000+ moving parts that actually writes programmable text — up to 40 characters — by dipping a quill in ink. The head and eyes move as it writes.
Think of it as a physical "LLM" from 250 years ago: deterministic, character-by-character output generation with a fixed instruction set. The mechanism uses a cam-based programming system where you can swap instruction wheels to change the text output.
Still operational today at Musée d'Art et d'Histoire in Neuchâtel. Peak mechanical engineering before electricity existed. The precision required to make this work with 18th-century tooling is insane.
Programmable output generation isn't new — the implementation stack just evolved from gears to GPUs.
