Would you do me the favor of explaining the joke? I get the premise—nobody cares about die size, but the comment being mocked seems perfectly innocuous to me? They want a laptop without an NPU b/c according to link we get more out of CPU anyways? What am I missing here?

It has been the norm for several decades to have hardware features that go unused.

The realities of mass manufacturing and supply chains and whatnot mean it's cheaper to get a laptop with a webcam I don't use, a fingerprint reader I don't use, and an SD card reader I don't use. It's cheaper to get a CPU with integrated graphics I don't use, a trusted execution environment I don't use, remote management features I don't use. It's cheaper to get a discrete GPU with RGB LEDs I don't use, directx support I don't use, four outputs when I only need one. It's cheaper to get a motherboard with integrated wifi than one without.
