In 1985, expert systems represented the primary hope for creating artificial intelligence capable of mimicking human cognition. These systems were designed to simulate the reasoning processes of human specialists across various professional fields. Key applications were developed for the medical, nuclear, and agronomy sectors. By utilizing specific programming languages, these tools could automatically replicate specialized decision-making. The goal was to capture human expertise within a digital framework to solve complex problems. This period marked a significant milestone in the evolution of AI development. It highlighted the early ambition to automate high-level intellectual tasks.
