New technologies can be adapted to better meet social needs or deliver services more effectively. Examples include computers in classrooms, the use of assistive devices for the elderly, or implants to cut teenage pregnancy. Through experiment it is then discovered how these work best (such as the discovery that giving computers to two children to share is more effective for education than giving them one each). Any new technology becomes a prompt. Artificial intelligence for example has been used in family law in Australia and to help with divorce negotiations in the US.
