Githubs copilote boosted the productivity of the programmers who use it by 55% allready. That is a prime example of an AI beeing used commercially, and not just for vanity but actualy productivity. Other fields will take a lot longer though, mostly because of stuffy management and a strong "never change anything" mentality a lot of workers have. But i think this will sort itself out rather fast as companies that do not quickly adapt to AI will be left in the dust.
