Great interview @ivanli ! (3k live viewers + compliments from David!!)
My takes:

• Iota would implement smart contract as a 2nd layer (not on chain).
• David doesn't approve the swiss-army knife perspective of Ethereum. Do one thing good.
• Take care not to fall on scams (like in every cryptos): create your own seed.
• Digital Currency Initiative (of Media lab) of MIT is a tiny, loosely affiliated, group with just brought FUD. (curlp was a copy-prevention mechanism).
• Extension hub for exchanges (not only crypto-exchanges) currently in testing
• Lightning Network cannot threaten Iota because of the on-chain transaction + routing problem leading to centralization (and fees). Bitcoin can only improve its technology but that's the same as using Iota directly, currently it is just unusable. In dynamic environment, you need to deposit multiple times with high fees.
• Flash payment system in dev during Iota hackathon.
• Blockchain (POW & POS) structure has opposite incentives (user vs miners) -> it gets
  Underlying protocole of Iota is decentalized when getting rid of the coordinator. Projects drive the adoption by organic growth ($50mln available for creating) or running a node.
• Roadmap 2018: #1 priority is grow/maturing the Iota fundation in Germany (for regulatory and industry) with processes in place + more manpower. Technology-wise, reach production-ready.
