What are the positive implications of technology?

There are many. The primary one being increased speed and efficiency in performing a vast multitude of tasks from manufacturing to communication. Others may include removing the need for humans to perform menial and dangerous tasks, an increased ability to understand nature and an increased standard of living for most of the world.

The complete list would be so long that many books could (and have) been written on the benefits of technology in fields ranging from medicine and microbiology to engineering and exploration.
