A fake chess-playing machine built by Wolfgang von Kempelen that appeared automatic but was secretly controlled by a hidden human is called what?

• A. Mechanical Turk 1770
• B. Fireflies.ai
• C. 3D printed mockups
• D. Makerspace

Answer: (A)

The idea being tested is a famous illusion of a chess-playing automaton that was actually controlled by a hidden human. In 1770 Wolfgang von Kempelen introduced a device that looked like it could play chess on its own, yet a person secretly operated the moves from inside a cabinet, making the machine seem truly automatic. This cleverly staged feat is known as the Mechanical Turk. It captured the imagination of spectators and sparked long-running questions about machines, intelligence, and what counts as a “thinking” device, long before modern computers existed. The other options refer to contemporary tools or unrelated concepts, so they don’t fit this historical hoax.
