That’s their excuse but it is convenient for them that in order to train the AI the workers need to follow the exact same steps as what an AI would be doing if it was sufficiently trained. We can’t say as outsiders to what extent the actual work is assisted by AI. Seems likely that it is largely a manual process.
I used to work in adtech and the most we could do was track locations. Even that didn’t work properly for our purposes because most shops are in malls where several different stores co-exist on the same coordinates. It only worked for outlets in retail parks which were separated from one another.
