A wafer looks pretty big. I'm surprised it has only 44GB of memory available. Doesn't that seem a tad .... low? I'm not a hardware person, but I would have assumed much more memory would fit into a wafer?

It's SRAM. It's the equivalent of 44 GB of CPU cache.
Exactly, which is why it’s so incredibly fast. And expensive.
SRAM doesn't shrink as well as other types of circuitry do when process nodes advance.
traditional SRAM memory has 6 transistors per bit. Dense SRAM can have two transistors.
Wafers can have trillions of transistors, 10-16 times more than the 4 trillion of the WSE-3.
1 Terabyte of SRAM per wafer will be the upper limit for a few years [1].

You mean it is unimaginably massive.
