Kranzberg’s laws of technology

Melvin Kranzberg’s six laws of technology state:

1. Technology is neither good nor bad; nor is it neutral.
2. Invention is the mother of necessity.
3. Technology comes in packages, big and small.
4. Although technology might be a prime element in many public issues, nontechnical factors take precedence in technology-policy decisions.
5. All history is relevant, but the history of technology is the most relevant.
6. Technology is a very human activity – and so is the history of technology.
