I once tasked an LLM with correcting a badly-OCR'd text, and it went beast mode on that. Like setting an animal finally free in its habitat. But that kind of work won't propel a stock valuation :(

It's mind-blowing the level of correction a modern LLM can achieve. I had to recover an OCR text that had about 30% of the characters incorrect. The result was 99.9% correct, with just the odd confusion whenever the suffix of a word could be interpreted either way and it picked one at random.
