Because it's not AI.
It's not "seeing" anything.
It's just taking a statistic generated from the data and finding the nearest data point to that statistic in its database and then returning it.
None of this stuff is "AI". This is why web filters are still just huge lists of human-checked websites, rather than something scanning each page to tell the difference between a pair of stockings modelled on the M&S website and something much more nefarious.
Stop calling it "AI".
Hell, stop calling it "recognition".
At best, it's an "algorithm".
