Thailand's National Electronics and Computer Technology Center (NECTEC) is celebrating 40 years of foundational tech development through NECTEC ACE 2026 (Sept 3, 2026). The conference frames Thai tech evolution across 4 decades: infrastructure (internet, semiconductors), policy-making (digital ministry formation), practical applications (Thai School Lunch, Traffy Fondue), and current AI/data focus. Director Chai outlined emerging priorities: AI sovereignty via Thai LLMs, humanoid robotics, medical AI using local data, EV charging tech localization, and space communications standards—signaling NECTEC's pivot toward next-generation challenges and potential SME collaboration opportunities.
