This article discusses the evolution of IT from past to future. It breaks the evolution down into four parts - past, present, future, and relationships. In the past, IT systems were basic and meant only for specialized programmers, but became more holistic over time. Currently, systems provide more comfort to users but components are breaking into smaller subparts. In the future, systems will become highly specialized and reduce human intervention. Relationships with machines will grow, requiring effort to maintain human relationships.
