Thai organizations struggle with AI adoption: 61% use AI partially but fall short of expectations, with only 10% succeeding as planned. Key barriers are lack of skilled talent (71%), unclear use cases, and unready data/infrastructure.

The article outlines a maturity framework: AI as tool → AI in application → AI as core process, emphasizing that success requires clear business impact, trustworthiness, cost efficiency, and scalability.
