Google becoming irrelevant is the most naive take in technology. It's more if wishful thinking. Google is equally, if not more relevant today. Their AI models are currently one of the best in the world. They still have a commanding search market share. YouTube and Android rule in most countries in terms of number of users. Chrome is the leading browser. Google maps is omnipresent. Gmail is the biggest email service online. Their revenues are steady.

They are not doing well with certain areas like social, GCP, messaging, enterprise etc. But it's not an existential threat.
