1. The new tool should be cheaper than the one it replaces.
2. It should be at least as small in scale as the one it replaces.
3. It should do work that is clearly and demonstrably better than the one it replaces.
4. It should use less energy than the one it replaces.
5. If possible, it should use some form of solar energy, such as that of the body.
6. It should be repairable by a person of ordinary intelligence, provided that he or she has the necessary tools.
7. It should be purchasable and repairable as near to home as possible.
8. It should come from a small, privately owned shop or store that will take it back for maintenance and repair.
9. It should not replace or disrupt anything good that already exists, and this includes family and community relationships.
I'm not sure even his own tool choices (typewriter and wife) meet the criteria. The typewriter replaced the quill pen, and at least initially failed conitions 1, 4, 8, and 9.
There might also be other factors for consideration. I'm not prone to jump on the latest technologies, but do own several computers (and a typewriter). Net effectiveness, suitability to task, expansion of possibilities, and other factors are amongst those I'd consider. Many of Berry's concerns would seem to me to come from the realm of unintended consequences, and might be better considered in that light.
His is a useful meditation, whether or not you adopt its conclusions.
