Sundar's comments about Google doing AI (really ML) are based more on things that people externally know very little about. Systems like SETI, Sibyl, RePhil, SmartASS. These were all production ML systems that used fairly straightforward and conventional ML combined with innovative distributed computing and large-scale infrastructure to grow Google's product usage significantly over the past 20 years.

For example here's a paper 10 years old now: https://static.googleusercontent.com/media/research.google.c... and another close to 10 years old now: https://research.google/pubs/pub43146/ The learning they expose in those papers came from the previous 10 years of operating SmartASS.

However, SmartASS and sibyl weren't really what external ML people wanted- it was just fairly boring "increase watch time by identifying what videos people wioll click on" and "increase mobile app installs" or "show the ads people are likely to click on".

It really wasn't until vincent vanhoucke stuffed a bunch of GPUs into a desktop and demonstrated scalable and dean/ng built their cat detector NN that google started being really active in deep learning. That was around 2010-2012.
