Before this publication, each genetic variant was tested individually, either in the laboratory or through models calculated one at a time.

A slow process that, according to statements by Pushmeet Kohli, vice president of research at DeepMind, would have required multiple human lifetimes to cover the entire combinatorial space of possible mutations.

The number of nine billion describes the breadth of the computational space covered.

What remains absent from the public announcement is an indication of what fraction of these predictions has been verified through experiments conducted on real human tissue.
