A teacher-built tool for a world that's changing fast: Why Maths3D exists, what it's built on, and who it's for. *EdTech as a public good in the age of vibe-coding* In 18 years within the education system — 16 teaching in state schools and 2 in the Ministry of Education — I have never been so deeply concerned about technology's (in particular AI's) systemic impact. As a parent to a young child, I am unsettled by the accelerating obsolescence of entry to mid-level roles. If AI erodes the traditional career ladder, the education system must pivot; we must ask how the next generation will reach senior-level expertise without the foundational experience and rewards of the "climb." I believe high-quality EdTech should be a public good, not a corporate commodity. While I cannot solve these global shifts, I am invested in mitigating their impact. For years, despite having coding knowledge, I did not have the frontend design knowledge to develop anything substantial. It was only with the advent of vibe-coding that I found an opportunity to address the gap in tools provisioned for teaching. Maths3D was co-developed with a $20/month Claude.ai subscription: built to a launch-ready state with ~120 prompts in four weeks — weekends and late nights — on a 13-year-old home laptop. This efficiency raises a sincere question: why should teachers, schools, or the Ministry pay premiums for platforms when AI tools can facilitate high-utility, in-house development? I am invested in making education systems slow such impacts. I teach an AI literacy course which includes students learning to vibe-code, providing them the agency to innovate solutions to their own professional problems. Anyone with a creative idea, problem-solving skills, and the perseverance to see it through now has the tools to bridge the widening equity gap. I seek to build and share AI-optimised tools — for schools and teachers that should not have to pay an arm and a leg for them — so that I may by whatever means enable my child and her generation to have a better chance of continuing to thrive in this brave new world.
