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
Meta's pause with Mercor leads to a temporary decline in collaborations within the AI space, with firms reassessing data handling protocols without severe long-term damage.
Enhanced security measures result in a stronger data protection framework for AI companies, fostering renewed confidence and innovation in the industry.
Continued breaches in the sector lead to a collapse of trust in third-party vendors, causing widespread operational slowdowns and potential financial losses.
