I strongly disagree. Without a shadow of a doubt, the most successful/important AI model of recent times is the Transformer (from Brain). As another example, the fastest accelerators, TPUs, are from Brain. If you only look at "amount of output" and use # publications at e.g. NeurIPS as proxy, Brain vastly outperforms Deepmind. Deepmind really exceeds at flashy and showy PR releases like AlphaStar, not so much at laying the groundwork for AI breakthroughs. (Though of course AlphaFold or AlphaGo were great).
