Google co-founder Sergey Brin recently shared the origin story of the TPU (Tensor Processing Unit).
Brin noted that Jeff Dean realized early on that just three minutes of voice usage by Google users was enough to double CPU demand. This insight drove Dean to strongly advocate for custom silicon. Larry Page and Brin fully backed the initiative well before AI became a critical priority, laying the groundwork for Google's current AI infrastructure dominance.
