Artificial intelligence meets old IT systems: How companies are stalling
Is the AI revolution being hampered? The challenge posed by outdated IT structures.
The rapid development of artificial intelligence (AI) promises enormous benefits to companies and governments around the world. From automating complex processes to improving decision-making to creating entirely new business models—the possibilities seem limitless. But behind the shining facade of the AI revolution lies an often overlooked obstacle: outdated IT systems.
The reality is often this: Many organizations still rely on IT infrastructures designed decades ago. These so-called "legacy systems" are not only technically outdated, but also structurally and conceptually unsuited to the requirements of modern AI applications. The result is a situation where the potential of AI is severely limited by the constraints of the existing IT landscape.

Why legacy systems are a problem
The problems caused by outdated IT systems during AI implementation are numerous and complex:
Compatibility issues
Legacy systems are often based on older programming languages (such as COBOL) and outdated software versions. These technologies are simply not compatible with the modern frameworks and libraries required for developing and running AI applications. Integrating AI into such systems often requires complex and costly modifications.
Data silos and poor data quality
In many organizations, data is distributed across various, isolated systems (data silos). This fragmentation not only makes it difficult to access relevant information, but also hinders the merging and preparation of data for AI applications. Furthermore, data in legacy systems is often in outdated formats or suffers from poor quality, which further limits its usability for AI.
Integration difficulties
Integrating AI into legacy systems often presents significant technical challenges. Outdated codebases, a lack of flexibility, and missing application programming interfaces (APIs) hinder communication and data exchange between systems. In many cases, extensive upgrades or even the replacement of entire platforms are necessary to enable integration.
Performance limitations
AI applications, especially those based on machine learning, require significant computing power. Outdated hardware and inefficient code in legacy systems often cannot meet these demands. The result is slow response times, limited scalability, and an overall reduction in the effectiveness of AI applications.
Security vulnerabilities
Legacy systems often lack the modern security features needed to protect against cyberattacks. Integrating AI into such systems can introduce new security risks, especially if AI platforms require access to sensitive data. Furthermore, security updates are often no longer provided for older systems, leaving known vulnerabilities exposed.
Real-world consequences: When AI initiatives stall
The challenges mentioned above often lead to AI initiatives stalling or even failing in practice. Some examples:
Healthcare
Hospitals and other healthcare facilities relying on outdated electronic health record (EHR) systems often struggle to leverage AI for tasks such as fraud detection, diagnostics, and personalized treatment. Data silos prevent a holistic view of patient data, and interoperability issues between legacy systems and modern AI tools hinder patient care.
Authorities
Government agencies, especially those dealing with large datasets and complex processes, often struggle with deeply entrenched legacy systems. These systems hinder the implementation of AI for tasks such as tax fraud detection, citizen services, and infrastructure management. Manual processes necessitated by outdated systems lead to inefficiencies and delays in service delivery.
Financial services sector
Banks and other financial institutions are increasingly using AI for fraud detection, risk assessment, and personalized financial products. However, outdated IT systems complicate the integration of AI-powered tools into legacy transaction processing systems. Data silos and incompatible formats hinder the effectiveness of AI, and stringent security and compliance requirements present additional obstacles.
Why modernization is a difficult battle
Modernizing IT systems is often a complex and lengthy process that involves a number of challenges:
Technical debt
Over the years, legacy systems often accumulate technical debt. This means that quick, but not necessarily clean, solutions were implemented to fix short-term problems. This "debt" significantly hinders the understanding, modification, and integration of AI into the code.
Budget constraints
The investments required for infrastructure upgrades, software replacements, and employee training can be substantial. This poses a significant challenge, especially for organizations with limited financial resources.
Resistance to change:
Employees accustomed to legacy systems may resist the introduction of AI. This can be due to fear of job loss, a lack of understanding, or simply convenience with existing workflows.
Lack of AI expertise
Implementing AI requires specialized knowledge and skills. However, many organizations lack the necessary internal expertise and rely on external consultants or service providers.
Bridging the gap: Strategies for AI integration
Despite the challenges, there are a number of technological solutions and strategic approaches that can help organizations bridge the gap between legacy systems and AI:
Middleware and APIs
Middleware can act as a bridge between legacy applications and AI models. APIs enable data exchange between incompatible systems without requiring a complete overhaul of the underlying infrastructure.
Cloud and hybrid AI solutions
Migrating AI workloads to cloud-based servers or edge computing solutions offers advantages in terms of computing power, scalability, and flexibility. Hybrid AI models, which combine legacy systems with new AI infrastructure, make it possible to run sensitive AI workloads locally while outsourcing others to the cloud.
Data modernization
Data cleansing, standardization, and transformation are crucial for converting legacy data into AI-friendly formats. ETL (Extract, Transform, Load) pipelines and data lakes can help manage data and prepare it for AI processing.
In phases, implementation
A phased approach to AI integration, where the technology is introduced layer by layer, minimizes disruption and allows organizations to learn and adapt as the process unfolds.
AI gateways
AI gateways are specialized tools that serve as an interface between AI applications and legacy systems. They simplify the integration process and accelerate AI adoption while maintaining the integrity of the legacy systems.

The price of antiquity: Economic consequences of neglecting AI
Neglecting the implementation of AI due to outdated IT systems has significant economic consequences:
Increased operating costs
Maintaining legacy systems is often expensive and inefficient. Specialized knowledge, frequent downtime, and ongoing repairs drive up costs.
Productivity losses
Slow and unreliable legacy systems lead to downtime and lost employee productivity. Inefficiencies also arise from data silos and the lack of seamless integration with modern tools.
competitive disadvantage
Organizations that fail to leverage AI risk falling behind their competitors. They miss out on opportunities for innovation, new revenue streams, and improved customer experiences.
Increased security risks
Outdated IT systems are more vulnerable to cyberattacks and compliance violations. This can lead to penalties, hefty fines, and reputational damage.
Catalysts for change: Government programs and subsidies
To promote digital transformation and the adoption of AI, governments worldwide have launched a number of programs and incentives.
Germany
The German government's Digital Strategy 2025 emphasizes the development of digital skills, AI, and the modernization of public services. Specific initiatives such as the "Digital Pact for Schools" and Germany's AI strategy are equipped with substantial funding.
European Union
The Digital Europe (DIGITAL) program aims to shape the digital transformation of European society and the economy, including the financing of AI, supercomputing, and cybersecurity. The EU's AI strategy and the AI Act are further key initiatives.
Global Strategies: A Comparative Look at International Approaches
Approaches to AI implementation and the modernization of outdated IT systems vary considerably between countries. Some rely more heavily on government intervention, while others prefer a more market-oriented approach. AI adoption rates also vary significantly, with some countries (e.g., China, the US, and Israel) leading the way.
Navigating the Compliance Maze: The Influence of Security and Data Protection Regulations
Security and data protection regulations such as the GDPR and HIPAA play a crucial role in shaping the adoption of AI. They ensure that personal data is protected and that AI applications are used ethically and responsibly. However, complying with these regulations can also present challenges, especially for data-intensive applications.
