Finance, decision-making, and AI interaction have been transferred to the digital economy due to the reduction of transaction costs and increase in security through blockchain technology. Integration of artificial intelligence (AI) and big data analytics with decision support systems (DSS), with a focus on risk assessment, predictive analytics, and strategic planning, has been explored. AI and DSS collaborated to deliver responsiveness and flexibility across several industries, leading to improved, data-driven decision-making. The current and future paths of AI with a focus on finance, healthcare, and customer service, in addition to ethical problems, have also been discussed. Future developments in the digital economy, such as cybersecurity, decentralized banking, and quantum computing, have been explored to optimize benefits and reduce risks.
