Having rewatched that myself the other day it's not actually as good an example as I thought - I use Claude 3.5 Sonnet a bit in it (which was released the morning we recorded that video) and then get a bit of benefit out of Val Town's integration with Codeium, which is similar to VS Code Copilot - but not as much of the code in it was LLM-generated as I remembered.
I would point out that the OCR example (and from what I see the series of posts you linked to) aren't "live" coding screen shares and don't convey the nitty gritty of how these things are used and how well they work.
A better (written) description of how I use these tools is this one: https://simonwillison.net/2024/Mar/30/ocr-pdfs-images/ - and this whole series of posts: https://simonwillison.net/tags/ai-assisted-programming/
