Which tech companies will be around in 100 years?
According to Russian billionaire Yuri Milner, Google, Facebook, and Wikipedia make the list of contenders. He attributed his choices to their overall "network effect"—the services they provide are so deeply embedded in our lives that we can't imagine living without them.
Milner was responding to a tweet at the South by Southwest conference in Austin, Texas, during a conversation with Bethany McLean, Vanity Fair contributing editor and a CNBC contributor.
When it comes to Google, Milner added, "I don't think we can function" if Google is shut off, even for a short time.
Milner's Digital Sky Technologies invests in later stage, founder-run companies. Facebook is, of course, one of them.
"I saw someone who was clearly a genius," said Milner of Facebook founder Mark Zuckerberg. "It didn't take me a lot of time to recognize that."
