I'm curious why I don't see any projects applying new ML techniques to text recognition (OCR) in those "advertisements" popping up recently; is this because:

- too boring/mundane?

- "solved problem"/too easy? (then where are the [open source] solutions? is Tesseract-ocr advanced enough already? what's its status?)

- too hard? (is Tesseract-ocr using the state-of-the-art techniques?)
