On 23 March, Microsoft launched a very public AI experiment.
The Twitter account @TayandYou was unleashed upon the web - an artificial intelligence impersonating a teenage girl with "zero chill". Tay would learn how to converse with the wider world based on interactions with humans, aimed at entertaining 18- to 24-year-olds in the US.
When a person Tweeted Tay, the bot would go looking for context for that individual's Tweet in order to frame a reply and "understand" what it was being asked.
On 24 March, Microsoft shut down its very public AI experiment, after things got very weird. This is what Tay tells us about AI, the web and humans.
