Grammar of obligation: syntactic patterns in Malaysian Reddit AIED Discourse

This paper examines how Malaysian Reddit discourse constructs the roles of the state, market, and individual in AI-facilitated education. Using Appraisal analysis alongside topic modelling (LDA and BERTopic), the study analyses public posts from r/Malaysia spanning 2024 to 2025, identifying three overlapping discourse frames: fiscal governance, corporate innovation, and individual obligation. These frames are interwoven to produce what we call a grammar of obligation, in which the modernization of education is described as a distribution of responsibilities across distinct social actors. The state is cast as a limited fiscal provider, corporations as technological enablers, and students as agents of constant self-adjustment. This tripartite arrangement encodes precarity and systematically shifts accountability onto individuals, framing employability as a personal outcome rather than a shared policy responsibility. Combining computational modelling with discourse semantics, the paper demonstrates how macro-level economic structures shape everyday public debate around fairness, competence, and value in the Malaysian context. A central theoretical finding is temporal misalignment across the three frames, whereby policy operates in the iterative present, technology in the progressive aspect, and individual obligation in the deontic future, normalizing coordination failure as personal navigational deficit. The findings illuminate how Reddit's participatory format reinforces neoliberal logic through registers of fiscal realism, pragmatic optimism, and credential anxiety.
