bitcoin currency and block technology was invented , if block technology universal in the world , we need a based on block search engine it ? google web-based search technology will be out of date it?
Google is a very stable company. I doubt that it will die just because of Bitcoin. I believe that when the time comes, Google will surely adapt blockchain and they might also create their own. We don't know, Google might be a blockchain based search engine in the future. If a company doesn't know how to adapt to technology, that is the time that it will surely dies.
