How does the usage/adoption of generative artificial intelligence technology affect the trust-building in projects?
6 answers
The adoption of generative artificial intelligence (AI) technology significantly impacts trust-building in projects across various dimensions. Firstly, the accuracy and reliability of generative AI outputs are paramount, as inaccuracies can lead to serious consequences such as false decision-making and the spread of misinformation, thereby affecting trust negatively. The journey towards wise usage of generative AI, as highlighted by Denning, suggests that building trust with these technologies is a gradual process that requires understanding and adaptation. In the realm of software development, trust in AI-powered code generation tools like GitHub Copilot is crucial for their adoption and responsible usage. Developers face challenges in building appropriate trust, which includes setting proper expectations, configuring AI tools, and validating AI suggestions. Addressing these challenges through design concepts that communicate AI performance, allow user configuration, and offer model mechanism indicators can support the trust-building process. Moreover, the widespread adoption of models such as OpenAI's ChatGPT and GPT-4 raises concerns about privacy, safety, and the erosion of trust in the public information ecosystem due to AI-generated fake content. These concerns underscore the importance of regulatory frameworks and the need for public pressure for AI regulations to ensure trust is maintained. Empirical evidence from billions of locality sensitive hash comparisons demonstrates the potential for verifying the "correctness" of generative AI output, which is crucial for trust, especially in decentralized networks. This verification process can detect perceptual collisions in AI-generated images and achieve consensus in large language models, thereby laying a foundation for trust through verifiability. Legal challenges related to copyright and the use of creations as training data for generative AI systems also affect trust. Ongoing lawsuits highlight the need for lawful use of generative AI, which could influence trust among creators and users. The adoption patterns of generative AI tools within software engineering, influenced by compatibility with existing workflows rather than perceived usefulness or social aspects, indicate that trust in AI tools is driven by their practical integration into development processes. Finally, the development of trust in the artifacts created by generative AI and controlling their creation is essential for user adoption, emphasizing the role of trust in the successful deployment of generative AI technologies.
