The semibrick conjecture

Let $A$ be an algebra, and call a set of pairwise Hom-orthogonal bricks in $\operatorname{mod} A$ a semibrick. Call $A$ brick-infinite if it has infinitely many bricks up to isomorphism. Semibrick conjecture. Every brick-infinite algebra admits an infinite semibrick. The source states that this conjecture follows from the second brick-Brauer-Thrall conjecture and was originally motivated by extension-closed subcategories.
