Sustainability has become an integral counterpart to technology in the innovation-driven modern world. The intersection of technologies and tools can boast unprecedented developments and upgrades daily. It has gone beyond Web 4.0 with the ever-expanding integration of educational use of technology. We integrate Artificial Intelligence (AI), Internet-of-Things (IoT) and Machine Learning in the project-based learning domain. This has changed how content is created and disseminated in educational enterprises worldwide. Sustainability, with reference to the globally acknowledged SDGs is a key feature of technology-integration in the classrooms. This paper offers a new concept called Skillgogy to leverage upon the trio of AI, IoT and ML, without missing the opportunity to mention some of the recently offered resources enabling a tremendous growth in audio content making. This paper also presents an assembly of PodMOOCs with sustainability in teaching English for Communication Skills.
