Lots of chiplet interconnects hurt your max performance pretty severely and drives up your complexity a lot. There's a reason they want to keep it monolithic.
I already harped on Cerebras, but their approach of just copy/pasting a whole bunch of identical functional blocks, over-provisioning the chip by ~8%, and then just fusing off blocks with defects allows them to effectively have 100% yield on a wafer-sized monolithic chip. This is very desirable, and just another reason I like their approach better.
