As an engineer, I spent most of my time working on developer tools, building IDEs, and studying human-computer interaction. I helped build a couple of startups, I built tools for JavaScript development, and worked on Firefox DevTools. But once I started to work with data scientists, all those code editors and IDEs that I knew as a software engineer suddenly stopped being the right tool for the job. Notebooks were. Notebooks as we know them today have many pain points (versioning, reproducibility, collaboration). They don't work well with other tools. They don't exactly encourage best practices. But none of these are fundamental flaws of the notebook paradigm. They are signs of a new computational medium. Much like spreadsheets in the 1980s. Two years ago, my co-founders and I start
