Why a startup is teaching human brain cells to play “Doom” - The Economist
Biological computing isn't science fiction anymore. A startup just trained human brain cells to play Doom—and it's renting them in the cloud.
Why it matters
A new compute paradigm is emerging: biological neural networks as an alternative infrastructure layer. This represents a fundamental shift in how AI/ML compute could be sourced and scaled, distinct from traditional silicon and potentially more efficient for certain workloads.
