Have you heard about the NIST synapse?

It sounded great until I read its works at temperatures close to absolute zero, and need to be cooled with liquid helium. That this might make the chips impractical for use in small devices, although a large data centre might be able o maintain them. … We don’t yet understand enough about the key properties of the [biological] synapse to know how to use them effectively.”

IST’s artificial synapse is a metallic cylinder 10 micrometers in diameter — about 10 times larger than a biological synapse. It simulates a real synapse by processing incoming electrical spikes (pulsed current from a neuron) and customizing spiking output signals. The more firing between cells (or processors), the stronger the connection. That process enables both biological and artificial synapses to maintain old circuits and create new ones.

Dramatically faster, lower-energy-required, compared to human synapses

But the NIST synapse has two unique features that the researchers say are superior to human synapses and to other artificial synapses:

No, I hadn't, and that's pretty impressive technology. But you're right. To go mainstream, technologies have to be able to function within a pretty broad range of temperatures, with room temperature being about average.
Superconductors are a problem in that respect, but I don't think that will always be the case.
We're creating new materials on a regular basis. Some found by accident.
Eventually, we'll have superconductors that don't require such special conditions to function.

No, they don't need to be in icy cold rooms anymore.
In a PC, I still look for a lot of ventilation, though.

I pray hope, pray dream of Quantum Computers that will simotaously explore every possible cure for autism, all Neurological Disorders and all incurable diseases.
I read Spectrum and other autism research daily. The lack of real solutions upsets and frustrates me more than words can describe. I have in the past received answers from researchers but, Spectrum people never respond.
Spectrum goes on political tantrums and complains about funding.
I support research funding but, the research must produce real results to make more people support them. Getting involved in politics is stupid for scientist.

Yes I am certain that is true. As a young adult I remember being called to the computer room. I had to meet and speak with people there. As soon as I walked in my first thought was I am freezing. Most computers no longer requires such cold.
