A book review for today.
But there is plausibly a show-stopping problem here. If someone announces they will upload my consciousness into a robot and then destroy my existing body, I will take this as a threat of murder. The robot running an exact copy of my consciousness won’t actually be “me”. (Such issues are richly analysed in the philosophical literature stemming from Derek Parfit’s thought experiments about teleportation and the like in the 1980s.) So ems – the first of whom are, by definition, going to have minds identical to those of humans – may very well exhibit the same kind of reaction, in which case a lot of Hanson’s more thrillingly bizarre social developments will not happen. But then, the rather underwhelming upshot of this project is that fast-living and super-clever ems will probably crack the problem of proper AI – actual intelligent machines – within a year or so of ordinary human time. And then the age of em will be over and the Singularity will be upon us, and what comes next is anyone’s guess.

I remember hearing an interview with the author of this book several months ago. I think the Guardian are playing the ‘horrifying future’ part up a bit too much; the author seemed to just see it as a thought experiment more than as a warning.
Happy reading
