Almost strongly compact cardinals, a natural weakening of strongly compact cardinals, have arisen recently as the optimal assumptions for certain category- and model-theoretic applications. An analogous weakening of measurability gives almost measurable cardinals. I will talk about a recent preprint of Mike Lieberman, giving a category-theoretic perspective on almost measurable cardinals.
