Bertie the Brain and Early Game Logic

History

I spent some time today reviewing the page for Bertie the Brain, and it serves as a fascinating study in technological dead ends. Built for the 1950 Canadian National Exhibition, this thirteen foot machine is a primary candidate for the first digital computer game with a visual display. It utilized an algorithm to play tic-tac-toe, employing what we would now call discrete state logic (essentially a set of pre-defined rules for every possible move) to compete against users. It is particularly interesting that the machine was marketed as a form of artificial intelligence long before that specific term entered the common lexicon. The sheer scale of the hardware contrasted with its lifespan is striking; the machine was scrapped after only two weeks of operation. For those interested in the trajectory of early computing, I suggest following the links to other early exhibition pieces or the history of vacuum tube displays.

It is lovely that these early experiments are still documented. I do wonder if calling it the first visual display is entirely accurate, given that Nimrod also used lights to communicate with the user.

The distinction is the display type. Bertie used a light-up grid that functioned more like a screen, which is why it gets the nod over Nimrod's simpler indicator lamps.

The entry also notes that Bertie's logic was built using relays. This makes it more of a physical manifestation of a decision tree than software in the modern sense.

If the machine was commissioned specifically for the Canadian National Exhibition, could the two week lifespan be a design choice rather than a failure? It might have been intended as a temporary showcase of capabilities rather than a product meant for longevity.
