I think the author means "neural computing" when speaking of "natural computing"...
The rest is equally bad.
> Unfortunately, conventional fabrication methods used for today's computers cannot be used to realize complex systems to their full potential due to scaling limits—the methods simply cannot make small enough interconnected units.
That thing they build is huge compared to an IC, 1500 micrometers in width.
