A charge-coupled device (CCD) camera with a light-sensitive electronic detector that Strojnik uses for her work, 1992. Personal collection. FROM STONE AGE TO FUTURISM As a scientist dealing with the future throughout her life, Marija sometimes specu- lates about what it would be like to live in the Stone Age. Her life expectancy would be short- er due to poor nutrition, but she thinks that that would not be such a tragedy because she would die before getting cancer three times. Since there were no lenses in the Stone Age, she would have to live without the optical technol- ogy that helps her see and navigate through un- chartered territory. In the Stone Age she would need good vision to find food, now she needs good vision (and a smartphone) to find her way in unfamiliar cities. Meanwhile, her children and their children will need intelligent cameras to guide them as they discover planets in nearby star systems. 75
