#12I'm surprised that no-one has discussed whether these systems could develop emergent qualia, and experience pain. No joke. Are there any ethical frameworks around this kind of research?

#14Pretty weird not to comment that they're replicating published work that trained mouse neurons on an electrode array to fly a plane in a flight simulator. https://www.sciencedaily.com/releases/2004/10/041022104658.h... It's about at the level where you could make a good attempt to replicate it as a hobby in your (albeit well stocked) garage.

Doesn’t hurt to join forces with another ‘well stocked garage‘ featured earlier on HN: https://youtu.be/V2YDApNRK3g

why did you link to the science daily and not any actual article? The linked page doesn't even link to an article, it links to a university press release. From 2004 no less. How am I supposed to verify that they are replicating published work as you say?

#18Using real neurons avoids hyperparameter tuning? Can someone explain how.
Re: A startup is building computer chips using real neurons
#19> 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. This seems silly. Once you've figured out these paramete…
Not true for modern neural networks. We typically use random values with certain statistics and/or specialized schemes which depend on specific later details - but in any case it's a single function call and the defaults typically work well enough that it's an advanced topic.
The OP is probably referring to neural nets of old, before this recent explosion, where you had handfuls of perceptrons operating on very simple problems which would be trivial for modern ML.
