I doubt it. To become Google you need a good few years of building up your IP and infrastructure. Google were very good at getting to be that big (biggest?) in a relatively short time and because they are so far ahead, anyone else will need not only to have better search, products (Android, Docs, Gmail, Self driving cars etc.) but also the infrastructure to match and exceed that of Google. By the time they get there, Google will be further ahead still. Perhaps in 20 years or so, the computing landscape would have changed so much that you'll have the entire Google infra in your brain implant or something like that but with all that progress moving forward, so will Google. I'm pretty certain they are here to stay.
