I once recognized a former football teammate from the stands years later when he was in full pads and helmet just from how he ran onto the field. No doubt an AI could be even more accurate, which is why I recommend wearing a mask and riding a hoverboard everywhere.

Thanks for reminding us that there are A LOT of different ways to recognize people! I had never considered looking at their gait, that sounds like cool research

that is a non-statement somehow; you aren't responding to anything I actually said, but what you imagined that I said, and then you came up with a counter argument to the imaginary statement...

the things people do really confuse me, sometimes. I .. I am just not capable of understanding why people do most of what they do.

I didn't say I wanted to defeat gait recognition, did I? No, I did not.

my turn to imagine something you'll say: "oh well you can also be recognized by your voice"

I didn't say I wanted to defeat voice recognition, either.
