You think artificial neurons stay “alive” for free?

Edit: but besides being cynical, I actually also don’t know how those biological processor can survive transport or just being a backup in a shelf

Not sure though, if I understand really what they are doing/have created.

Edit 2: pretty much everything is answered in the article. Seems they really need some “food” and there is also the problem, that they will need to be retrained periodically (until a solution is found) l, because the culture dies (and builds new)
So, thinking about shelf life and transport was a bit far out the way
