Scientists have created a fully biodegradable artificial synapse using chitosan from crab shells, plant fibers, and bean extracts. The device operates at just 0.85 femtojoules per signal, making it more efficient than the human brain while retaining memory for nearly 100 minutes (the longest ever for biodegradable synapses). The breakthrough potentially paves the way for AI hardware that learns, adapts, and dissolves without toxic waste.

Ah, finally, a way to make more AI crap. Because we needed to have more of it.

If there's a breakthrough to make the technology cheaper, more efficient, and less polluting, I'm all for it even if I hate AI. It's not like corporations are going to stop while they still see profits to be had. Pushing them towards better/less harmful options is likely the best we can do.

That's why the effort needs to be done to stop AIs legally, and by disabling profit from them (or disabling capitalism altogether but that's another subject), not by continuing to maintain the hype and investments in AIs.

This is not LLM hardware, these are artificial neurons for research.
