Each year, AI enthusiasts compete for the Loebner prize, which pits chatbot against chatbot to see who or what can come closest to passing that test.
While more sophisticated methods of machine learning are in development, many of today's chatbots are still built on a similar coded call-and-response formula as ELIZA.
I tried talking dirty to a handful of BDSM-themed bots: As it turns out, the most popular gay scripts involve a decent amount of abuse and shaming.
Like ELIZA, many of these scripts are trained to recognize and respond to keywords and phrases.
Meanwhile, Google has developed its own proof-of-concept chatbot to show off the power of neural networks, which mimic the human brain.
