Will it ever be possible to bring back people like Sasha? I don't know. There's nothing in our current understanding of physical law that would permit such a thing even in principle, but we don't know everything about how the universe works; maybe some future understanding will give a different verdict.
<br><br>But it's not something that merits argument. There's a distinction to be drawn between ultimate vision and current effort.<br><br>Most people (myself included) need some sort of transcendent vision to inspire them to work towards a brighter future. Different visions work for different people; the idea that our dead might ultimately be restored is a beautiful one, and will be all the more so if it turns out to be true; let those of us who can't quite believe it acknowledge the unknowability and hold onto something that does work for us.
<br><br>The environmentalists have a saying: think globally, act locally. That's exactly what we need to do, except in time rather than space. Let's not confuse the ultimate and the imminent; rather let our transcendent visions inspire us to work on projects that can be realistically accomplished in the foreseeable future. Does it make sense to work today on a resurrection machine? No. Does it make sense to work today on, say, molecular electronic computers, with the idea that they might be a step on the road that eventually leads to the dead being restored - and will have a lot of other applications before then? Absolutely.
<br><br>"Think globally, act locally" - I wish I were that good at coining phrases! It would be nice if we did have an equally snappy temporal version - any ideas anyone?<br><br>Happy 2007!<br>
