As I said near the end of the video, this is a research project meant to demonstrate the concept and a lot of engineering would need to be done to make it work generically. If a small team were to tackle the project, I estimate it would take about 2-3 years of effort.
That said, I prefer Python and only used JavaScript in the video because I had a large project done in JS that I wanted to validate the idea against to make sure it wouldn't just work for toy programs.
