Its a device problem. Until he buys different device, it will stay. Now, we can figure out why his specific device is the only one to have such problem, but for that, we generally need screen shots, browser type and device type. It could be browser issue, it could be device issue. So my first suggestion for him is to try a different browser, just to see if problem is there.

No, it is just word predicting program. They did put guide lines so it avoids some harmful and obviously false or bad content, but thats about it. It just predicts next word. The quality of AI is based on how good is it at predicting next word.
