P4 programmability is available in Cisco Silicon One so wouldn’t call P4 dead in the water. Cisco Silicon One is meant to go head to head against Broadcom. https://www.cisco.com/c/en/us/solutions/collateral/silicon-one/datasheet-c78-744312.html https://www.cisco.com/c/en/us/solutions/collateral/silicon-o... In other merchant silicon, while not P4, Broadcom has offered their own proprietary programmability in Trident 3/4. I think adoption has been slower more due to lack of relevant domain expertise in software as well as relative inability of pretty much anyone to properly model the impact of routing features on a production network than anything else. P4 is being widely adopted at the NIC level.
