Vitalik: The Ethereum priority should be to improve interoperability between L2 and L2

Vitalik Buterin said at the AMA event that the Ethereum priority should be to improve interoperability between L2, because there are not too many Stakeholders, everyone has a common interest, so the process will be much simpler. Then it can be scaled up to do more cross-crypto interoperability, even from cryptocurrencies to fiat currencies.
