1. The desktop is not dead for GIS work. While web apps are popular, the desktop remains important for starting GIS projects and performing complex spatial analysis. Desktop GIS work can then be shared to web apps.
2. Maps are a powerful part of GIS but spatial analysis and processing adds even more utility. Background tasks like joins, exports, and analysis can be done and results visualized through maps.
3. While the web has disrupted some areas, GIS is also disrupting the web by bringing location and spatial analysis to more web services and applications. Standards like REST and JSON have helped GIS integrate with the web.
