简介：法律是保障一切事物正常发展的大前提,在技术领域特别是牵涉到大家生命安全的研发尤其需要法律的规范,比如这几年发展特别迅猛的自动驾驶项目。当大家都在热烈讨论并且自觉国内的自动驾驶技术研发已经接近国际先进水平时,有没有想过发生事故该怎样划分责任?研发单位肯定想过,政府部门肯定也想过,但是相应的法规却迟迟没有出台。法律没有及时跟进的理由非常多,条条都冠冕堂皇而且解释得通,但是结果会很可怕,并且最终将反过来遏制自动驾驶技术的发展。

简介：摘要随着经济的发展，供电企业源源不断的为社会提供商品电力，并从中收取电费，电费作为供电企业最主要的经济效益，是企业赖以生存和发展的重要支柱。电费是电力企业生存和发展的根本，是电力企业发展的必要要件，做好电费收缴工作也是电力企业的重头工作之一。电力企业改制以后，电费的收缴问题一直成为困扰我们企业发展的一个重要问题。

简介：法律的核心功能是维护社会规范性期望的稳定，法律通过“深度不学习”的方式成功化约了社会复杂性。而在人工智能为代表的认知性技术兴起之后，学习能力的急速提高将深刻改变传统法律的特征，法律的计算化和社会科学转向是其典型表现。大数据、区块链、智能合约、模拟仿真等技术应用正在持续改变法律的功能形态，催生出“小法律”“实验法”等新型学习性法律。从法律不学习到机器学习，将在法律空间、法律时间、财产形态、信用机制、法律自由、法律正义等各个方面产生深层效应。根本性的挑战在于法律功能独特性的丧失。法律不学习被机器学习取代，规范性期望被认知性期望取代，法律被代码/算法取代，这也就是法律“死亡”的前景。
