You are welcome to not use Google or its services. Contrary to popular belief, if you don’t actually use any Google services, they will know very little about you.
Similarly, you can also not use Facebook (I don’t!) and not use Instagram and not use any other service you don’t like. Works pretty well!
That being said, a good web search engine, whichever one you choose to use (duckduckgo?) is absolutely crucial to succeed in almost any profession these days. If you haven’t yet learned a good way to express the kinds of searches you need to find results, and how to browse the list of results that come back to guide your attention to what’s a good answer or not, you are falling behind, just like people who didn’t learn to drive a car fell behind when horses went out of style.
