Final answer:
Financial Services are hesitant to move to the cloud mainly due to security concerns, the risk of system failures, and the potential for increased technological dependence and vulnerability.
Step-by-step explanation:
The main reasons Financial Services are reluctant to move to the cloud include concerns about security risks, regulatory compliance, and potential system failures. The fear of technological dependence, especially in the case of crucial systems, such as those running nuclear power plants or the banking system, intensifies the need for robust security measures. Moreover, the potential for a bank failure can create uncertainty and risk, which makes the financial sector cautious about transitioning to cloud computing. Additionally, reliance on technology can widen the digital divide and add to the vulnerability of the nation's technological infrastructure.
