If you roll back 200 years, everything you now see around you is science fiction.
We've managed to move a lot of things from the realm of science fiction
to science fact in the mere 45 years I've been around.

I don't recall having mentioned a particular time frame. I actually
agree that in 20 years we should be able to progress to build fully
functional macrosacle devices capable of walking off the staging area,
but that's about it.

Why, a ~um voxel depositor capable to integrate sensors, actuators, logic
and power into an extruded block is exactly that.

You don't need to be able to specify 300 nm flat surfaces down to ~0.1 pm
in order to build useful objects. ~um at up to ~mm to ~cm total deposited layer
across A4 to A3 surface would do plenty.
We can do atomic-scale manipulation of some ~100 species in 2d, but it's

I could build you that today, if you can find small diamond wafers acceptable.
However, this is not what we at all need.
