It turns out that 90 per cent of us watch videos on Facebook with the sound off (probably to avoid the embarrassing scrabble to find the mute button in the middle of an office deep in thought, or to avoid the horrified stares of fellow commuters shocked at your disturbing their post-work torpor).

AmEx and BBR Saatchi & Saatchi tapped into this this statistical knowledge and hid a nice surprise in a video promoting a Guns ‘N Roses gig. For the 10 per cent of fearless listeners who watched the video with the sound on, the voiceover let it be known that the first 50 people to reply with the name of the lead singer would get tickets for the concert.

There was a state of panic this week when it appeared that Facebook’s AI-trained chatbots had created their own language that we mere humans weren’t able to understand. We were guilty of pondering how long it’ll be before post-apocalyptic fictions become real life and the robots take over.

Mashable advised us to ‘stop freaking out’, describing it as “hardly the doomsday scenario so many are seemingly implying”. They were meant to be learning to trade and barter with each other, the plan being to create chatbots with the ability to converse, reason and negotiate. As the Mashable article points out, the most remarkable result from the experiment (which had been omitted from other reports) was that the bots taught themselves to lie. Still a sinister outcome even if the new language doesn’t mean we’re soon to be under the rule of the robot overlords.
