But would you let one manage your relationships with other humans? by Tim Maughan 20 June 2016 In an age where we increasingly communicate via email, text messages, and social media posts instead of face-to-face, it can be hard to judge whether we are getting the tone right. Without the non-verbal cues we take for granted when talking in person with someone – or even on the phone – it can be hard to know whether what you're saying is being taken the right way. But what if there was an app for that? Would you trust a piece of software to communicate with your boss or your loved one for you? McNeil believes people might be ready for some assistance with these kinds of tricky communication tasks. We sometimes outsource it to our friends because this is just a constant problem. For example, when you meet someone and you like that person, people often have friends 'workshop' their texts. If you're trying to set up a date with someone you might reach out to a bunch of your friends and say, 'what should I say to this person? ' There's a wonderfully cheerful, realistic advertlike video that explains how it might work. "It was important to us to build a functioning app, so that it would go beyond speculative design fiction or sci-fi," McCarthy says. "Because it is a real app, when you encounter it, you are faced with choices and questions." Let's employ the technology!

Therefore if Maria goes out, Axel will fail the maths unit.
