For example, if a fully autonomous car causes an accident, who should be liable for damages to the victim? If the cause was that it learned from incorrect data, is there any point in punishing the car itself or the AI installed in it? What about a case where an AI analyzing an X-ray image overlooks the shadow of a cancer, and the attending physician also overlooks that oversight? These are all issues related to technologies that do not exist yet but are likely to be realized in the near future. It is not clear whether current positive laws such as criminal law and civil law can be applied effectively, and even if they can, whether the results will be desirable and acceptable to us. Nevertheless, society demands that we imagine the direction of technological evolution and design a legal system to guide appropriate outcomes in preparation for 'that day' which will surely come. I, too, am assisting in this work along with many AI researchers and engineers.

「世界が根本的に変わる」「これまでの法制度は無用になる」といった声は常に聞かれます。しかし社会や技術の進化に対応して自らの姿を変え続けてきたのが、共和政ローマで作られた十二表法以来、2500年に及ぶ法の歴史です。そこで生み出されてきた理念や概念は、これからの世界を想像し、それにふさわしい制度を創造するためにも役立つでしょう。過去に学び、未来を創り出すことが求められているのです。
