#2The concept of using human neural networks instead of artificial neural networks is both terrifying and intriguing.

#3They should also compare human brain cells with chimp/dog/... brain cells. See if the human ones perform better, which would suggest there is an advantage even at the lowest cellular level.

#5Paywalled. From an earlier article in Forbes:
> Using real neurons avoids several other difficulties that software-based neural networks have. For instance, to get artificial neural networks to start learning well, their programmers usually have to engage in a laborious process of manually adjusting the initial coefficients, or weights, that will be applied to each type of data point the network processes. Another challenge is to get the software to balance how much it should be trying to explore new solutions to a problem versus relying on solutions the network has already discovered that work well.
> “All these problems are completely eluded if you have a system that is based on biological neurons to begin with,” Friston said.

The other main advantage is low power consumption.
> AlphaGo, the deep-learning system DeepMind created to play Go and which beat the world’s best human player in that ancient strategy game in 2016, consumed one megawatt of power while playing the game, enough to power about 100 homes for a day, according to an estimate by technology company Ceva. By contrast, the human brain consumes about 20 watts of power, or 50,000 times less energy than AlphaGo used.
However, it's not clear whether these hybrid chips will have similarly low power consumption.

Paywalled?! I don’t see a paywall here, maybe I’m still in the”free articles limit”. By the way thanks for your quotes!

#8How do they do it in practice? How do the neurons know when they succeed / fail?

#9Is there published research? Looking through verious reports, all I see are references to the New Scientist article.
