There is no "solved" in computer vision, there is only "good enough" and what constitutes "good enough" depends on your problem domain.

Take an OCR model with 99.9% character-wise accuracy. Sounds pretty good, right? Well if your use case is, say, digitalizing old printed novels, then yeah it's probably good enough.

But what if your documents are personal records with millions of names, to insert in some administrative database? Now 1 out of 1000 persons will have their name misspelled. Ooops.
