An exciting result to be sure, but the article fails to address issues I'm interested in, which I can only hope I will find in the journal. I'm not a biologist or biochemist by any stretch, but I do have a keen interest.

Depending upon the selected definitions of species and evolution. *grin* (I know, stubborn to the core... )
However, even I would have to concede this round, assuming that the research is valid (which I suspect it is).
I only need once more bit to make me really happy, and that would be somebody creating life from inert components. (In other words, making life without using anything that was made by life. Injecting DNA into an existing cell body, or using existing cells as engines to create custom DNA don't count. I'm talking about life from raw elemental components. Something that has yet to be accomplished.)
Do you think it will ever happen?

They are able to make synthetic polynucleotides, so that's a good start. No idea if there is work being done in trying to create life out of raw materials though.

Yes; unless tripis is wrong about evolution, which I don't believe to be the case. (I argue against it to try and understand the other side, but I am a firm believer in evolution.)

"But building life from scratch, from the "bottom-up", is a challenge that some synthetic biologists have decided to take on. "

Basically any1 that says it's impossible should be seen as the people that said we would never find the blueprint to life, DNA.
Read the whole article. They are making cells which aren't really "cells", it's crazy ass shit. Loving it, can't wait to get to grad school.
Here's another one: "Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.
Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.” http://www.msnbc.msn.com/id/20249628/

If your talking about proteinoids I think your faith is placed in the unknown potential, not in science.
Demonstrating how life can or did arise will be difficult unless we're missing a huge part of the picture.
Very entropically disvarored reactions are required in ginormous numbers under any view.
Right now we can say a number of things could happen, but they're very unlikely to happen, and I doubt we'll ever crack that.
Fact is we're here, so I'm not trying to appeal to a texas sharpshooter fallacy, but it would be very difficult to show a model of how life began with actual experimental results in any signifigant portion of the neccesary sequence of events.

EDIT:
Misinterpreted what you said... You're just saying its not impossible to create life, right?
Depending on your definition I'd say that's right, but has little relevance to the liklihood that our current beliefes, about the origin of life, are accurate, or what the odds of life arising are.
