The Critical Engineer recognises that each work of engineering engineers its user, proportional to that user's dependency upon it.
A critical engineer's work is understood to have an effect on its user corresponding to degree in which the user relies on it. Thus, the more a user depends on the work, the more they will be influenced by its content.
This is an interesting thought regarding the relationship between a product and its user/audience. I can see this belief reflected in popular culture regarding the prevalence of smartphones in our current society. It is often joked that as our phones become "smarter" we become less so. Nowadays, it is easy to see the influence technology has on our lives. Recently, research has shown the detrimental effects of blue light on our Circadian clock, our postures suffer due to long hours in front of a computer screen, and average time spent outdoors is quickly decreasing. In the same way our technology is continuously engineered and altered throughout the years, so have our lifestyles. Because of this, the fifth tenet of the "Critical Engineering Manifesto" rings true.
