Is Goguen the most crucial part? When will it be launched?

Full question from another Forum thread:
Is Goguen the most crucial part for Cardano to be finally usable in terms of smart contract execution and dapp building? And when is the timeline for Goguen to be launched?

Answer: Goguen is the development phase covering smart contracts. We will have smart contracts before we have a dapp platform. The smart contracts testnet is now live, with Plutus playground and Marlowe Meadow. Look out for updates as to when mainnet will launch.
