> We demonstrate fungal computing via mycelial networks interfaced with electrodes, showing that fungal memristors can be grown, trained, and preserved through dehydration, retaining functionality at frequencies up to 5.85 kHz, with an accuracy of 90 ± 1%. Notably, shiitake has exhibited radiation resistance, suggesting its viability for aerospace applications

Soon we'll have shiitake replacing transistors in our airplane and spacecraft computers, while sitting and eating ramen on the vehicles themselves. The future is shaping up to be interesting.

What it makes me think of is 'cybernetics' research from the 1960s when it was not a foregone conclusion that transistors, especially CMOS transistors, were the future of computing. Back then there was a lot of research into alternate models of computation, something that's only becoming relevant today as CMOS may be running out of steam.

I recently read The Unaccountability Machine (which I can recommend btw), which mentions Stafford Beer's experiments with a computing pond. Who knows, maybe we'll control our factories with mushroom brains soon!

How is this related to that at all? The fungi they used are clearly dead...
