Maybe not in the sense of "A site where you enter text and find pages containing that text". Just like Microsoft Windows might never be replaced as the most popular Desktop OS. Desktop OS just become less and less important.
But certainly in the sense of "A way to get answers to your questions". I expect computers to learn about the world and give answers directly. Just like image recognition software can tell you the answer to "Does this image has tomatoes?". Software will be able to answer "Do tomatoes grow in China?". Or answer "Paint me an image of tomatoes in China" the way Googles deep dream net can already "paint" lots of things [1].
It will be interesting how this turns out for "content creators". When computers learn and become creative, there will be no more SEO :) Because your site will just be read and ingested by a bot and make it better to answer questions. No more clickt-hroughs to your website.
