It was also a different Google, the "3 different teams working on 3 different chips" bit reminds me of lore re: how many teams were working on Android wearables until upper management settled it.
FWIW it's a very, very, different company now. Back then it was more entrepreneurial. A better version of Wave-era, where things launch themselves. An MBA would find this top-down company in 2025 even better, I find it less - it's perfectly tuned to do what Apple or OpenAI did 6-12 months ago, but not to lead - almost certainly a better investment, but a worse version of an average workplace, because it hasn't developed antibodies against BSing.

Google was changed by two things, neither of which were much fun. But very understandable.
One was the transition to a mature product line. In the early days it was about how do we do cool new things that will delight users: Gmail, Google Maps (Where 2), YouTube. The focus was on user growth and adoption.
Then growth saturated and the focus turned to profitability: Getting more value out of existing users and defending the business. That shift causes you to think very differently, and it's not as fun.
The second was changing market conditions. The web grew up, tech grew up, and the investment needed to make a competitive product skyrocketed. Google needed more wood behind fewer arrows and that meant reining in all the small teams running around doing kooky things. Again not fun, but understandable.
I wasn't on Brain, but got obsessed with Kerminology of ML internally at Google because I wanted to know why leadership was so gung ho on it.
The general sense in the early days was these things can learn anything, and they'll replace fundamental units of computing. This thought process is best exhibited externally by ex. https://research.google/pubs/the-case-for-learned-index-stru...
