Easy, from my recent chat with o1: (Asked about left null space)

‘’’ these are the vectors that when viewed as linear functionals, annihilate every column of A . <…> Another way to view it: these are the vectors orthogonal to the row space. ‘’’

It’s quite obvious that vectors that “annihilate the columns” would be orthogonal to the column space not the row space.

I don’t know if you think o1 is magic. It still hallucinates, just less often and less obvious.

average humans don't know what "column spaces" are or what "orthogonal" means

Average humans don't (usually) confidently give you answers to questions they do now know the meaning of. Nor would you ask them.

And why would the "average human" count?!

"Support, the calculator gave a bad result for 345987*14569" // "Yes, well, also your average human would"

...That why we do not ask "average humans"!
