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
Data vendors with strong security protocols will emerge as preferred partners, while those without may struggle to maintain client relationships.
Increased demand for robust cybersecurity measures could lead to growth in cybersecurity firms specializing in data protection for AI companies.
If breaches continue without resolution, investor confidence could wane, leading to decreased funding for AI startups relying on external data sources.
