Neural organoids can be cultured and maintained for months at a time (we grew fairly attached to the one my coworker was growing). Even the measurement wiring can be sustained for months.
I've worked in biology and computation for decades (and fascinated both with intelligence and artificial intelligence the whole time), but seeing a timelapse of a bunch neurosphere forming over a few weeks from some tiny stem cells, with all the neurons sort of self-organizing themselves by spreading lamellapodia (https://www.youtube.com/watch?v=fniW9EiOmUk https://www.youtube.com/watch?v=fniW9EiOmUk) a few years ago flipped a switch in my head. I used to think the development of the hardware to support intelligence was a really tough, complicated problem. It's clear that the structure of neurons is absolutely primed to build semi-random networks that can be adapted to signal processing and computation in an almost "trivially easy". Obviously there's tons going on under the hood at the molecular, cellular, and organoid levels
It's funny but some technologies have a way of going from "sci-fi" to "ho-hum" quickly, and I think "rat neurons playing DOOM" is a great example of that.
Looking a little at the neuroplatform, it looks like they grow the organoid in a microfluidic container and can maintain it functionally for months. Seems like an opportunity to sell the computer as a subscription (new organoid package every month?)

One interpretation of the “when is it conscious” question is it’s really asking “when do we start to care about it,” and I love that the answer for humans is often “as soon as we start spending time with it.” > It's funny but some technologies have a way of going from "sci-fi" to "ho-hum" quickly I’m a programmer working in biotech, and the things that have become de rigor in the field are the stuff of sci-fi from a decade ago. It’s incredible.
