Observable https://observablehq.com/collection/@observablehq/explorables is having a meetup in SF https://ti.to/observablehq/meetup/en and I'd love to see future of coding folks there! Observable is • almost-JS in a notebook interface that uses the DAG of your code to reevaluate spreadsheet-style • runs using your browser's JS engine, not on a server • leans into the visualization use case but is a very general platform aka hopefully sufficiently non-revolutionary to catch on

You could also post this to #CG8QU2QUU, it's more relevant there.
