CIOs are cautiously evaluating the value proposition of generative AI assistants like Microsoft's Copilot and Google's Gemini amidst concerns over costs and uncertain returns on investment. While AI tools can significantly enhance productivity in specific roles such as programming, where they help clean up code and find security issues, the broader application in general office tasks remains dubious. Some organizations, like the University of California, Riverside, and IT consulting firm Thoughtworks, are hesitant to commit to widespread adoption due to unclear ROI and substantial per-user expenses. However, specialized AI assistants tailored to specific roles demonstrate more measurable productivity gains, indicating significant future potential.
