Physicists Say That Teleportation is Unworkable

When you're criticising others for making simple errors, you probably shouldn't make them yourself. I am, for instance, unaware of any hard drive that can hold one human's data at the specified magnitude of 10^42 bits, let alone 'billions of people', let alone you saying that they need to use more data to describe the human.

Hrm... also, the hard drives we have at the moment are in the order of 10^12... so you'd need 10^30 drives... at which point, it's cheaper (and no slower) to just send the person in their place.

There's no reason to assume the 10^42 bits is an accurate measure. Most likely, there's significant compression that can be done on the data, both lossless and lossy that can bring the storage requirements down to a much more reasonable level.

My apologies, I should have checked the math, I didn't look too carefully and in frustration posted that number. I was also directing this at the 'physical' reconstruction, where only 1.2 x 10^10 bits are required. Clearly this wouldn't be billions but it's still thousands.

10^42 is the Bekenstein bound, you cannot possibly require more data as that represents the quantum state of the system.

A billion would be ~10.37 exabytes, or ~300 petabytes with lossless compression (ideally).
