And so the heat dissipation seems to be the major point of this news. Will be interesting to see a more technical writeup or some published papers on this.
Does anyone know by what metric it will be 1,000 faster? It seems like a technique for having massive numbers of cores in parallel, but I'm not sure how the adhesive would address any specific improvements to the cores themselves. That said, even if it's just a way to get 1,000-core CPUs or whatever, it sounds like a remarkable breakthrough.
Seems like you're still generating the same total amount of heat, that needs venting from the machine. And still consuming the same amount of power.
I'm sure there's some value here, but it's not going to arise from just stacking up the same chips we use today.
What would this mean for the global economy?
The same as always, more "value", specialization and jobs created which means more money for the rich and less money for the poor.
A miracle glue will not solve power dissipation problems, not even if it were a perfect thermal conductor.
So this is a way of dissipating heat more efficiently, such that chips can be apparently be stacked on top of each other -- does that really help all that much for consumer (and especially mobile) stuff?

A lot of wait states in a CPU come from accessing memory outside of cache. If you make all the RAM in your system the same as cache, you'd get a huge leap.
Funny how everything goes 3D these days. Cinemas, TV sets, handheld consoles, and now even our CPUs.

This could have quite an impact on CPU-bound cryptographic algorithms.
A massive, massive improvement in compute might hasten SHA-1's demise, but SHA-1 is already on life support today.
It is unlikely that even a huge unexpected leap in compute power would change the fundamentals of how things are encrypted today. Unless something like quantum pans out, you can expect us to still be using RSA (or more likely ECDSA and ECDH), AES (or something like one of the eSTREAM finalists), and HMAC-SHA3 for the foreseeable future.
The thing that will change what our crypto stack looks like will be a new discovery in cryptology, not a new way to build super-cheap, super-fast processors.
