Sure, but Apple's doing pretty well there. Think of the apple silicon as a chiplet. Said chiplet has a 400GB/sec memory bus, 8 performance cores, 4 efficiency cores, and 38 gpu cores (not to mention accel for video encoding, matrix multiplication, and AI. Said chiplet is sold in 1 and 2 chiplet configurations today (max and ultra flavors of the chip) and have a very healthy chip<->chip connection 2.5TB/sec. No reason Apple couldn't add some glue to allow more than 2 chiplets in a package.
