No, we didn't. There are tens of thousands of developers writing smart contracts. Some of these smart contracts, such as Uniswap (https://uniswap.org/), have traded more than $1.2 trillion in volume. Uniswap works 24/7 with 100% uptime. It's permissionless to create a liquidity pool or to trade on the platform. It's a novel architecture, called an Automated Market Maker, a real innovation in financial markets. Uniswap is fully auditable thanks to everything being on-chain. Source code is open. There's also on-chain lending markets (Aave: https://aave.com/), decentralized stable coins (https://www.liquity.org/), on-chain arbitration (https://kleros.io/), on-chain DAO governance (https://compound.finance/governance), on-chain social media primitives which are extensible (https://www.lens.xyz/), multi-sig on-chain smart contract wallets that custody hundreds of millions to billions in assets (https://gnosis-safe.io/), decentralized strategy games that use on-chain zero knowledge proofs to maintain a fog of war and player secrets while keeping everyone honest while allowing for full hackability (Dark Forest - https://zkga.me/), etc. Can really go on and on, but the industry is not going anywhere.
