Are there connections between Homotopy type theory and Grothendieck's theory of motives?
Downvoting because this question consists of little more than "X and Y are cool. Is there any kind of connection between X and Y?"

Properties of schemes determined by field valued points
@solbap. One example you probably already know. If $X_{/\mathbf{C}}$ is proper, then the analytic space $X(\mathbf{C})$ "knows" $X$ by GAGA theorems.

Is there a higher Grothendieck ring?
It wouldn't strictly be a generalization, but note that you could take $K_n(\mathrm{Mot}^\mathrm{num}_k)$, for $\mathrm{Mot}_k^\mathrm{num}$ the category of (numerical) motives over $k$.

Cohomology of Lie groups and Lie algebras
For what it's worth: using
\ast
for asterisks avoids this problem, as in $H^\ast(g(Q))$
