The 5 sectors most impacted by artificial intelligence

1. Health

Predictive medicine and personalized diagnostics

AI is transforming healthcare and the pharmaceutical industry by improving diagnostics and treatments tailored to each patient. Advanced algorithms analyze millions of medical records to identify patterns and predict diseases before they become severe. This approach, predictive medicine, allows healthcare professionals to provide more accurate and targeted care.

Generative AI and LLM in Healthcare

LLMs are now used to analyze scientific literature on a large scale, accelerate the search for molecules and write clinical syntheses. In France, Doctolib integrates AI to optimize appointment scheduling, emergency triage and diagnostic assistance in community medicine.

Automation of administrative tasks

Automating case management, appointment scheduling, and patient follow-up allows professionals to focus on care. Generative AI also makes it easier to write medical reports, reducing administrative time significantly.

2. Finance and the banking sector

Predictive analytics and robo-advisors

In the financial sector, AI is used for predictive analytics, allowing institutions to predict market trends. Robo-advisors offer personalized financial advice based on customer behaviors and preferences.

Fraud detection and compliance

AI has become the first line of defense against fraud: it analyzes transactions in real time and identifies suspicious activity. In banking and insurance, analytical AI detects and prevents money laundering (AML) schemes. LLMs now allow thousands of pages of regulatory documents to be automatically analyzed for compliance.

French example

BNP Paribas has deployed AI solutions for automating the processing of market transactions, real-time fraud detection and optimizing customer relations via intelligent chatbots. To learn more about the AI challenges in this sector, see our article on AI in banking.

3. Retail

Intelligent Inventory Management

AI helps retailers optimize inventory management by predicting demand and automating replenishment processes, reducing storage costs and stockouts. The procurement function is particularly benefiting from these advances.

Customer Experience and GenAI

Retailers are using AI to deliver a personalized customer experience online and in-store. Generative AI now makes it possible to create hyper-personalized product descriptions, marketing visuals, and recommendations at scale.

French example

Carrefour has launched an LLM-based conversational assistant to help customers compose menus, compare products and get nutritional advice directly from the mobile app.

4. Manufacturing

Predictive maintenance

AI enables predictive maintenance of industrial equipment, reducing downtime and repair costs. By analyzing sensor data, the systems predict failures and plan maintenance in advance. For more information, check out our article on AI in industry.

Smart Supply Chain and GenAI

Production lines are becoming more efficient thanks to AI, which optimizes processes and reduces waste. LLMs are used to analyze quality reports, automate technical documentation, and accelerate problem solving in production.

French example

Safran uses AI for the predictive maintenance of its aircraft engines, the analysis of flight data and the optimization of manufacturing processes in its French plants. According to the PwC 2024 barometer, industry is the French sector with the highest demand for AI skills.

5. Transport and logistics

Autonomous vehicles and flow optimization

The transport sector is changing with the development of autonomous vehicles. These vehicles use machine learning algorithms to navigate safely. The self-driving car market is expected to grow by 22.75% between 2024 and 2029.

AI and logistics

Supply chain and logistics use AI to optimize delivery routes, predict peak demand, and manage warehouses autonomously. LLMs facilitate the analysis of supplier contracts and multilingual communication with international partners.

French example

SNCF is deploying AI for the predictive maintenance of its rail network, the optimization of real-time schedules and the improvement of the passenger experience via conversational assistants.
