There is no solution to Ethereum scalability problems. Consider it to it's way to graveyard.  If a singe blockchain game CryptoKitties can take up to 20% of transaction volume of whole network and slow screw it down, just imagine what will happen after similar games will be launched? If the situation will not stabilize, all of us will switch to NEM, NXT Bitshares or Waves. Vitalik is just enjoying his millions and laughing hard.
