Is that actually an internal Google goal? If so, dear god, no wonder they are so willing to sacrifice the long term health of the internet in return for short term hypergrowth. No company Google's size can grow that fast without some serious dark patterns and user abuse.
You don't end up with that level of growth year over year for 20 years straight by accident. It is an unwritten assumption that missing 20% growth is a fail. I worked at Google almost 10 years and watched the dog and pony show (aka TGIF) from the inside. The real story is on the quarterly financial reports.
