William pursues a career in genetic engineering, referred to as homology, and has been trying to understand and cure autism, hence his chosen surname. Anthony has gone into telemetrics, and is working on the Mercury Project, the purpose of which is to send a robot to Mercury. This is a problem because the positronic brain at the time is not yet adapted to such an environment, so a computer on Earth must direct the robot.
William focuses on genetic engineering, known as homology, with the aim of understanding and curing autism, which is why he chose his surname. Anthony has entered telemetrics and is working on the Mercury Project, whose goal is to send a robot to Mercury. The issue here is that the positronic brain at the time isn't prepared for this environment; therefore, computer control from Earth is necessary.
