The title of this article is misleading; they're not putting people's *consciousness* into an artificial body, they're putting people's previously-frozen, or cloned, *brains* into artificial bodies, which is a whole other ballgame.
In the first case you definitely won't live forever -- even if your brain somehow physically survives the freezing-and-thawing process, there's the little matter of restarting the extremely delicate physical (chemical and electrical, to start with, and probably quantum, if recent research holds up) processes that cause a MIND to emerge from the MEAT, so to speak. I have no doubt it will take many more than 30 years to master that trick. Even if they do, "you'll still be you" only as long as *that particular brain* survives (with one possible loophole); once you've been recorded and played back into a developing clone brain, *at best* you have a whole new individual who *thinks* he's you, who *remembers being* you, and whom your friends and family may well *accept* as you -- but there's no continuity of your consciousness: the "original you" *ends* -- dies -- and a new, "pseudo"-you begins. They could give pseudo-you your original brain in a jar as a birthday present. Heck, they could create pseudo-you while original you is still alive, if you need ultimate proof that he's a whole separate person.
The loophole is to hook up your original brain to the clone brain in realtime, so that your mind "runs" on both simultaneously. At first, run it 100% on your original brain and 0% on the new one, but gradually let the new one pick up more and more of the load -- 99% vs 1%, 98% vs 2%, ... 1% vs 99%, 0% vs 100% -- 'til you're running entirely on the new brain. Consciousness would be continuous and I myself would be willing to undergo the process.
The sucky part is that "forever" is an awfully big claim. You'd have to undergo the process again every brain-lifetime -- and eventually things will change and they won't be able to do it anymore: society will collapse and they'll forget how; or the tech will change so much, or humans evolve, so that you're in an old format they can't read anymore; or someone will arbitrarily decide to say "no" for reasons of their own, or ... well, *anything* might happen. "Forever" is a long time.
Too, your brain has only so many neurons or subatomic particles or whatever it is that does your thinking; these can assume only so many different states or configurations; and eventually you will go through them all and reuse a state you've been in before. You'll start to repeat the same thoughts you've had before. If "they" can detect when you start to repeat, that might look a lot like a reasonable point to tell you "no."
The loophole here is to keep moving your consciousness into ever-more-capacious hardware. Since you're already using artifical bodies, artificial brains shouldn't be too much of a stretch, once the technology becomes available. Then you just keep building them bigger and better, and you're all set -- except of course for that business about society forgettng how, or somebody saying "no" for their own reasons...
