Under your feet right now, a living, breathing network more complex than any human-made system stretches for miles. Fungal threads weave through soil, connecting trees, plants, and ecosystems in a giant net that has existed long before humans walked the Earth. This talk explores the secret life of mycelial networks—nature's original communication system. From packaging that grows itself to computational models that mimic fungal communication, this talk reveals the untapped potential hidden beneath our feet.
