There are other search engines: Bing, DuckDuckGo, etc.<p>In a large parts of the world, Google isn&#x27;t even the biggest search engine. In Russia, Yandex has 60% of the search market[1]. In China, Baidu is the biggest search engine, with 57% of the search market.[2]<p>And if Google were to shut down, new companies might enter the market.<p>As for Gmail, there are hundreds of competing e-mail services. And there are competing map services, smartphone operating systems, etc.<p>It&#x27;s debatable how much Google really changed the world, since it wasn&#x27;t the first company in any of these markets. They had a new and clever search algorithm, but their competitors have also improved over the years.<p>My primary search engine is DuckDuckGo, and I rarely use any of Google&#x27;s services. If Google disappeared tomorrow, I might not even notice.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Yandex" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Yandex</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Baidu" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Baidu</a>
