The article seems pretty optimistic to me. Toward the end of the article there is a mention in passing of the need for "exotic matter," meaning matter with negative energy/mass, and the fact that we have never encountered such a thing (with the exception of the Casimir force, which is very small), is a big hurdle, or rather a potential deal breaker, in the sense that if it exists, then OK, but if it doesn't exist, then then the drive won't work. So until we find exotic matter, it seems a bit over optimistic to talk about progress being made.

Push a button, press a petal, and that fancy drive system whose workings no one can explain will send us to another location in space-time.For a journo attempting to support the intellectual credibility of a notion, you'd think he'd get his spelling right?
.. Or at least, ask someone else to proof read it before publishing?

Perhaps he was imagining that the Alcubierre drive would be located in a field of flowers. :)

Indeed. A field of poppies might be a better solution to space travel than exotic matter.
