I barely feel confident to judge myself as a whole person wtf.

I think that would go backwards to, someone would compute alignment directly, and notice this operation occurring in the computation.

For dot product, I'd say linear combinations are a pretty natural thing to think about, and at some point, one would realize you could/should represent the coefficients as a vector as well.

Felt the same way in Montana, bitch this wasn’t even a state during all that.
