According to Andrew Ng (@AndrewYNg), the contributions of Project Jupyter co-founders Brian Granger (@ellisonbg) and Fernando Pérez (@fperez_org) have been foundational in enabling the widespread adoption of coding notebooks in AI and data science. Jupyter Notebooks, as noted by Ng, are now essential tools for prototyping, experimentation, and reproducibility in machine learning workflows, accelerating innovation and collaboration in both academia and industry (Source: Andrew Ng, Twitter, Oct 25, 2025). This open-source platform has also spurred a growing ecosystem of AI-focused extensions and commercial services, creating substantial business opportunities for enterprises building products on top of Jupyter infrastructure.
