A World Model of Life: Biohub's Alex Rives on Virtual Cells, Measurement, & the $1.8B Data Push

Biology's AI bottleneck is measurement technology, not models — Biohub is spending $1.8B to generate the missing data.

• $1.8B data push: Biohub's expanded Virtual Biology Initiative pairs with DOE, NIH, Google DeepMind/Isomorphic, and Meta to map cellular biology across hundreds of billions of cells.
• Measurement, not architecture, is the bottleneck: Rives says today's virtual cell models fail mainly because observation technology can't capture fine-grained causal biological data, not because of weak AI architectures.
