These scenarios are not guarantees. They show the most likely path, the upside path, and the downside path based on the evidence available now.
The most likely path, plus upside and downside
Regulatory bodies impose guidelines prompting firms to enhance their data security measures without significantly disrupting operations.
Heightened awareness leads to industry-wide standardization of data security practices, improving overall resilience and potentially enhancing market confidence in AI technologies.
Further, more severe breaches occur, resulting in loss of trust and a significant downturn in investments within the AI sector.
