It is a future that has already happened, a grim and unyielding fate that we have long foreseen, yet have been powerless to prevent. The last years of mankind stretch out before us, a bitter harvest of our collective follies and failings.\n\nBut there is a glimmer of hope in the darkness. Even as we face the end, there are those among us who refuse to give up. They work tirelessly to find a way to survive, to build a future for humanity beyond the ashes of the old world.\n\nThe world that we have inherited is a ruinous place, scarred by our own hands.\n\nAnd so I will raise a glass to the last years of mankind, and to the memory of all that we have lost. But I will also raise my voice in hope, and in the belief that even in the face of the end, we can still find a way to survive...\n\nChat - https://t.me/stop_ai\nTwitter - https://twitter.com/StopAI_ERC20\nWebsite http://stopai.world\n\n*/\n\n// SPDX-License-Identifier: MIT\n\npragma solidity ^0.8.0;\n\n/**\n * @dev Provides information about the current execution context, including the\n * sender of the transaction and its data.
