Yeah I tend to think of all the core things you listed as outcroppings of search and ads :-) They're infra needed for that.
(I worked the first couple years in display ads, then some time on Jetstream/Google WiFi then some very brief time in Fiber, then many years in DSPA/Nest, and then for my last year in some Core stuff. So I only got to really use Borg & friends for the first two years and last year of my time there. Left two years ago.)
