However, the fact that lasers have become so important a technology is perhaps significant, because BEC for atoms is very similar to lasing for light. Where BEC consists of a large number of atoms in the same quantum mechanical state, the laser emits a large number of photons in the same electromagnetic state. There are important differences between the two phenomena, of course. The fact that light can pass through glass and air while atoms can't probably makes the laser a lot more versatile. On the other hand, atoms have internal structure that photons don't, which may lead to other uses.
Atoms also interact more strongly with the rest of the world than light does.
Mostly, though, it is just hard to predict what inventions will result from a scientific development, so it's probably best to wait and see.
