This week on Tech Weekly with Aleks Krotoski we meet American playwright Jennifer Haley, whose play The Nether runs at the Royal Court theatre in London until 9 August. Jennifer discusses her exploration of the the dark side of virtual worlds in the not-so-distant future, and why technologies that recreate perfectly experiences and sensations also throw up deep moral and philosophical questions.

Aleks is joined by Jemima Kiss, Alex Hern and Samuel Gibbs to discuss some of this week's big tech stories, including the hacker who revealed that Uber is rating you, and it's not just about you rating the driver; and Google put their money and might behind scientific research to understand what being physically healthy actually means.

Julia Powles and Jat Singh from St Johns College Cambridge discuss why the internet of things poses huge risks to online privacy. Julia and Jat discuss their recent article on the issue and why the law needs to catch up with these technological developments.
