Chiplet designs means that you still have to route signals either onto an interposer or onto a PCB. If you have a silicon interposer you have the same issue of making a really large silicon die. If you route into the PCB, then you may need SerDes depending on what you do and bandwidth will be lower and latency will be higher due to signal integrity issues.

Maybe something like Intel's EMIB technology where they have small interposers along edges of chips rather than having a giant interposer might help here.

Yields are probably fairly good if they design for manufacturing by placing extra cores / wires to route around failures as I am sure they are.

The future of these interconnects is to make them optical. Once the interconnects are optical lots of problems get solved. Chips don’t have to be in same enclosure, simplifying cooking etc.

I will dissent. Organic interposers are dirt cheap, and nearly as good unless all you want is density.
