Re: HP's 'Crossbar Latch' to Replace Transistors (?)

paragraph 7

"While current silicon transistor technology can also perform the same operations and restore signals, the researchers generally believe that transistors will not be able to shrink down to the size of a few nanometers and remain operable"

The $64,000 question = how many is a few ?

I googled it a bit out of curiosity and discovered the linked article; from that...

Silicon wires less than 1 nanometre long bridging between conductors act as conductors rather than semi conductors because quantum effects from the conductor electrons act on a larger scale than the structure of the silicon wire and extend into the wire. So 2 or 3 nanometers may be a bottom limit for the dimensions of semi-conductor/conductor interfaces.

But then you would need very different manufacturing tech and I dont know how cost effective that might be, but as a wild guess we might be looking at devices one tenth the scale of current.

So I wonder if that means an X-box will be (in 20 years) the size of a gameboy ?

Do I care ?
