Final answer:
There isn't a direct statistic provided in the references regarding the percentage of CEOs who believe AI will play a key role in the future of their businesses.
Step-by-step explanation:
The question about the percentage of CEOs who predicted that artificial intelligence would play a "key role" in their business's future does not include a direct statistic from the provided reference material.
While the references discuss the considerations and potential impact of AI on society and the workforce, including concerns about data privacy, job displacement, and corporate responsibility, there isn't a specific survey result cited that gives us the exact percentage of CEOs prediction on AI's role.
However, industry leaders acknowledge the importance of AI, recognizing its presence in leading industries and the potential for increasing global GDP, as indicated by Goldman Sachs. They are also aware of the ethical challenges and the practical need for proper governance.
