Generally speaking, we're not at the point where we need 32GB of memory or more for gaming, or even for most tasks outside of content creation chores. That might not always be the case, however, and for users who game on the go, Samsung is now mass producing the first-ever 32GB DDR4 SO-DIMM memory modules.

As pictured above, SO-DIMMs (small outline dual in-line memory modules) are shortened memory sticks used in laptops and mini PCs like Intel's Next Unit of Computing (NUC). Before now, the largest capacity single SO-DIMM module was 16GB.
