$91 million of Polkadot ICO funds, Gavins ICO. Gavin a cofounder of Ethereum, and the creator of Solidity.
So its more like the cofounder of Ethereum lost $91 million dollars in his own wallet, using his own smart contracts, using the language he wrote.
I am against the proposal to undo the deleted multisig wallet contract. Everyone makes mistakes, some are worse than others. You can never learn if every mistake can be undone.
