I just discovered this video: http://www.youtube.com/watch?v=M7JYZviFH54
And the strange thing is: at some point these things will actually work.
What does that mean for us?
This process makes traditional VLSI obsolete. The cost of manufacturing computers would be so drastically reduced (No more expensive PCBs, packaging and so on) that building a customized chip-based application specific asic would be no longer needed.
We simply would have 10^5 to 10^7 processors on a large silicon device (Using 180-32nm with 8 inch wafers)
And if you research a little there are already some companies willing to touch the subject again...
