Singularity or Biological Life Extension?

I'm reading a book by the title, "Designer Evolution: A Transhumanist Manifesto." It is about transhumanism but solely from the philosophical side. It is a little bit preachy, but I just happen to agree with almost everything Young has to say. I generally focus on the technical side so it is a much needed change in perspective as well. Anyhow, it got me to thinking about biological life extension a la Aubrey De Grey and the singularity. There is no mention of the singularity in the book just yet and I wonder if the author is aware of and interested in it. It seems there is a bit of a dichotomy between those interested in biological life extension and those seeking let's call it silicon-human integration. Do these two camps meet up and talk? Do they share similar ideas? Are they really on the same page, but I just haven't read enough about them all yet?

I've also been thinking about which will come first. I wonder if humans will have achieved drastically increased biological lifespans before a singularity event occurs. A singularity may or may not bring about increased lifespans whether they be carbon or silicon is unknown. Would people rather live in a biological body but keep a backup of their mind a la Cory Doctorow? I'd wager it might be that way at first, but eventually people (beings) will migrate towards a fully virtual lifestyle.

And if someone blogs a blog on blogger but no one is around to read it, does it really exist on the interwebs? Oh well....
