Mirror – less about skin-deep feedback. More a way of looking into your conscience.

We get told technology will save us, but how come every time another teenager gets stabbed in the middle of the day in a crowded part of London, the CCTV is too blurry, the police alert so slow, the punishment so low tech and the education that might solve the problem at source, so low tech for the user? We have 3D printers that can print out all kinds of building materials yet we have a massive housing shortage. Why can’t these two things be joined up? We have electric and hybrid cars. We have pollution-absorbing man-made materials and air vents. But central London has streets with incredibly levels of air pollution. Why can’t technology be deployed on this yesterday?
