The TCS conference is just about to begin its final plenary, which includes an author of personal interest to me, N. Katherine Hayles. Her book, Becoming Posthuman, has been a central reference point for my own ideas on posthumanism over the last few years. It's also relevant for my forthcoming, co-authored book 'The Medicalization of Cyberspace'. This is my first TCS conference and it's been a rich mix of ideas and presentations. It's also a good excuse to visit Tokyo for the first time, where we've already had a typhoon and an earthquake!
