Bitcoin itself is moving away from pure Blockchain. There'sd a "second layer" network in development called Lightning, and most transactions are going be performed on that. The Blockchain itself will be reduced to a "settlement layer". (This is not without some controversy). Of course, the underlying Blockchain will still be there. And it will always be possible to build other "second layer" solutions to compete with Lightning. Similar things are in the works for Zerocash and Ethereum.
