These circuits must be quite speedy to require this kind of inter-chip connection technology.
High costs always inspire innovation, so that's a bright note:
"Some chip start-ups are deliberately avoiding designs relying on CoWoS, which can require months to design the required interposer.
“Didn’t want to touch it,” said Sha Rabii, a co-founder and the president of Majestic Labs, which is designing an A.I. processor that can use simpler packaging and cheaper memory chips. “It takes a key part of the supply chain challenge off the table.”"
