Barefoot didn't die -- they were acquired by Intel, who has continued to invest in it with the development and introduction of Tofino 2.[0] Moreover, P4 is not/was not Barefoot alone; to take an example that's relevant to us, the P4 application working group working on the In-band Network Telemetry Dataplane Specification[1] includes participation from Alibaba, Arista, CableLabs, Cisco Systems, Dell, Intel, Marvell, Netronome, and VMware.
Disclosure: We are using both Intel Tofino 2 and P4 at Oxide and we (obviously?) think it's pretty interesting.
