Can Ethereum ever scale?

Read an interesting article http://reason.com/blog/2017/07/26/ethereum-blockstack-blockchain-freedman
in which Princeton Computer Science Professor Michael Freedman is convincing on why its very hard to scale to support a large transaction volume. It is difficult to build a distributed system that is optimized for multiple things. Right now it is optimized for global consistency and it comes with many trade offs include transaction volume, application layer features etc.

  1. How many full nodes are running on Ethereum network? Why so little? Can you still call it decentralized? Or why would you ever?
  2. Why Ethereum blockchain is already bigger than Bitcoin's? How big it will be by the end of next year? TB? Whaaaaat?
