I would like to encourage him to (also) add IF NOT-principles (because some earlier technologies actually perform (in certain situations) better than contemporary ones and some technologies became obsolete by more recent inventions)
Could you name some examples?
An example would be runners along the andean road outperforming horsemen but being outperformed by cars (and modern communications).
An acient technology of refrigeration (wet sand) currently receives renewed interest because of eco-friendlyness.
