A good airplane will fly from Mexico to San Francisco, coming to rest at the airline terminal. The minor trials and tribulations posed by more mundane examples of bad technology may not be of such titanic proportions, but they differ only in scale, not quality. Software which crashes instead of running is bad technology, obviously. Telephone systems which connect you to India instead of Indiana are not usrful. Doing 'what you want it to do' is a highly personal thing.
Parents often criticize teens' clothes because they represent bad technology.
If you want clothes to protect you from the cold, then your daughter's selection of light chiffon and an ultra-mini represents bad technology. But if you want clothes to accentuate your physical features, then the same clothes represent good technology. Technology should do exactly what you want it to do. Technology which does something else, either by design or by accident, is not good technology. Don't try to force bad technology in to the mold.
