Over a decade ago, I worked on a presidential papers project. The audacious goal was to scan in all presidential papers, make them available for download, and extract any possible data. But until the advent of the typewriter, virtually no data *could* be extracted, other than the odd letterhead. My proposal was to collect the images, build a processing pipeline, and when OCR of handwriting was possible, do it then.
Well, ChatGPT *nailed* this. So many handwritten documents can be discoverable!
