Alphabet was seeing around 15% YoY revenue growth prior to 2021. Then 2021 hit and the growth rate jumped to 41%. Now with the 6% YoY growth this year, it's evening out to ~22% annualized growth over the last 2 years.
As long as consumers are buying stuff, companies will advertise to them. As long as Google has a captive audience and they can continue to mint keywords for advertisers to bid against, I think this flywheel continues.
