He could not fathom modern technology; he simply could not wrap his head around it. Today's society is increasingly dependent on technologies such as cell phones and computers. While their widespread usage is undeniable, a deep understanding of how these technologies operate remains elusive for many. This lack of knowledge can lead to difficulties in making informed decisions about the use and governance of technology.
