Google is one of the most valuable companies in the world, but its future, like that of all tech giants, is clouded by a looming threat. The search company makes virtually all of its money from ads placed on the World Wide Web. But what happens to the cash machine if web search eventually becomes outmoded?
Now Google is melding these advances into a new product, a technology whose ultimate aim is something like the talking computer on “Star Trek.” It is a high-stakes bet: If this new tech fails, it could signal the beginning of the end of Google’s reign over our lives. But if it succeeds, Google could achieve a centrality in human experience unrivaled by any tech product so far.
