Motivated by Bott periodicity, we study the space of algebraic maps from $\mathbb{P}^1$ to the full flag variety $GL_{n+1}/B$. Under a mild positivity condition, we show that the class of this moduli space in the Grothendieck ring of varieties is given by $[GL_{n}\times \mathbb{A}^D]$. In a special minimal degree case, these varieties are isomorphic and that proof fits on a postcard. This is joint work with Jim Bryan, Freddie Manners and Ravi Vakil, and a part of this project involved a collaboration with Google Deepmind, in particular with George Salafatinos.
