I dare say that its because it's more effective there? I surmise that AI is quite effective at doing finance task (like identifying data in a pile of document an spitting out an Excel spreadsheet with it), a little less in legal (like the lawyer who used AI without checking and AI invented legal precedents because it wasn't trained on a real precedent database and "learnt" that lawyer-y documents often cite precedents so generated them...) and more difficult to use in visual arts (cause it's difficult to generate consistent content) and even more difficult to write a long, convulted plot with branches like a videogame needs? Adoption should start where AI tools can achieve "profesionnal-grade proficiency" earlier?
