While these are amazing performance numbers, I seriously wonder if all this expensive AI magic will be cost effective in the end.<p>Their lead example is recommendation systems, but I can't say that I have received many good suggestions recently.<p>Spotify and Deezer both suggest the chart hits, regardless of how often I dislike that kind of music.<p>Amazon keeps recommending me tampons (I'm a guy) ever since I've had a coworking office with a female colleague in 2015.<p>For all the data that they collect and all the AI that they pay for, these companies get very little revenue to show for it.
