Why use chips when you can use real brains?

Lab grown brains have been around for a long time, but this is the first time anyone's tried to do meaningful computations with them.
Turns out, neurons are neurons, doesn't matter if they're real or artificial.
I love their headline - "training an AI model consumes 6000 times more power than a European city".
So, divide that by a million, and now we're down to a city hall, or a police station.
Still a lot. These researchers haven't figured out criticality yet.
This research uses actual human brain tissue. The only problem with this is the neurons eventually die. In a real human brain they're replaced (daily - in fact every 30 minutes or so), but the researchers haven't figured out that part either.
The super-amazing thing about the human brain is, information is faithfully transfered from dying cells to the new neurons. No one's figured that out yet - but there's a group at Boston University looking into it. The medical term for neuron replacement is "neurogenesis". The best known example is the cells that feed the dentate gyrus in the hippocampus. They are located in layer 2 of the entorhinal cortex. They turn over at a rate of about 1500 per day.

The bioprocessor platform consists of brain organoids instead of silicon chips and processes data while consuming a million times less power.
