Close, things like PCI and AGP (i.e. fast/wide parallel busses), not PCIe.

Everyone in the late-90's recognized that parallel was maxed out and GHz SerDes with embedded clock recovery, adaptive equalization, lane skew compensation, error detection, etc. was the future. Future I/O (IBM, HP, Compaq, 3Com, Cisco, ...) and NGIO (Sun, Dell, Intel, ...) were competing efforts that eventually merged and then rebranded by Intel as InfiniBand. But IB had the usual design-by-committee disease as it tried to shoehorn in networking, io, and system interconnect roles. Intel then bailed from the effort and serialized PCI instead. Intel tried to get back into that game in the 2010's with OmniPath without success.

Thanks. Had a feeling I may have been wrong with "PCIe" term specifically, but couldn't be bothered looking up the exact details. :)
