>My prediction is that, as unimaginable as it seems, we'll be able to scale down to the physical limits of the materials.

What are these physical limits of the materials?

[sqeaky]

Whatever they are, there will be some other materials that will let get lower....

Until we are building on a single atom, and even then maybe we can go smaller.

>even then maybe we can go smaller.

Can you elaborate?

[sqeaky]

We simply don't know what the smallest thing we can compute with is. A material scientist might say that the smallest silicon traces that can do the are X nanometers, then another will come along and say he is right, but we can use gallium-arsenide to get down to X-5 nanometers. And this progressive 1 upping has fueled Moore's law

There are people doing research on subatomic who think that various quarks have interesting properties for computing. This may or may not be possible. But we likely don't know yet.
