Education has been heavily affected by the introduction of Generative Artificial Intelligence (GAI), such as ChatGPT and Gemini. Due to its recency, it is important to understand the public perspective on GAI and to assess its benefits and drawbacks on education. A number of studies have been conducted, but they mostly rely on academic literature reviews. While such studies are reliable, they might be less timely than those relying on social media or news. The findings might not be holistic. Therefore, we employ three different content sources to capture the holistic perspective of GAI: social media (X/Twitter), news (Google News), and academic literature (Google Scholar). A total of 3932 contents are analysed via sentiment and thematic analyses. We found that GAI has promising benefits like improved work productivity and access to vast amounts of information. The use might be encouraged in education. However, some concerns have been raised, including misuse and over-reliance. Penalty and identification mechanisms might be needed. It is also expected to prohibit the use on some assessments to prevent over-reliance. Educational stakeholders could integrate GAI in their learning environments with clear policies.
