I am totally in favour of removing limits on human life span and think it's an inevitability rather than a possibility (although I don't expect it to happen in my lifetime). Here is why I disagree with some of the objections made to it in this article.

No Jobs for the younger generation - I think the notion of requiring someone being forced to have job to earn a living is another concept that will eventually be regulated to the past. However, that's my post scarcity fantasy and it's very likely life extension will come before that. We're at 7 Billion people now we're still find jobs for them. An economy is about people, and more people means more economic activity.

The planet won't be able to support all the people - This is correct, although the planet can support more than we think, especially with cleaner and more efficient energy sources. Even if it turns out to be a huge problem, it would hopefully have the benefit of pushing us to expand to other parts of the solar system and universe. An extended or unlimited life span it would make it viable to for people to travel the long distances involved.

Evolution will stop - I'm of the belief that mankind's real evolution is now happening in its shared intelligence. We're already starting to gain the ability to bend DNA to our will. Biological evolution through natural selection is not the way forward for us.

Boredom - Perhaps. We really don't know. Hopefully the lack of a natural death would force us to finally create sensible laws regarding the ending of one's existence. It would be nicer to have a choice when to leave the party, rather than be forced out the door.
