Prominent science fiction author and blogger Cory Doctorow is considering leaving the U.K. Why? Because it's becoming uncomfortably like the old Soviet Union:
I asked her why she didn't stay, and she shook her head like I'd asked the stupidest possible question. "It was the Soviet Union", she said. She waved her hand, groped for the answer. "Papers," she said, finally. "We had to carry papers. The police could stop you at any time and make you turn over your papers." The floodgates opened. They spied on you. They made you spy on each other.[...]
The identity card I'm to be issued when I renew my visa is intended to be linked to all my daily activities: my medical care, my use of transit, my banking and finance, my tax – a single identifier that will track me through time and space, forever. [...] We are encouraged to spy on our neighbours and report their suspicious activity. We can be stopped and searched with no particularised suspicion, and during these searches, police officers can and do examine such things as the books we're reading and the personal notes we've made. [...] If the government of the day when I renew my visa in 2010 requires that I carry these papers as a condition of residence, the Doctorows will again leave their country and find a freer one. My wife – born here, raised here, with family here – is with me. We won't raise our British daughter in the database nation. It's not safe.
Very scary stuff... I can't put it any better myself. Also see Charlie Stross's post on this subject, for more links and context.
