Intel did this is 1989 with iAPX 432. Super interesting and SUPER complex (just check out the documentation of cpu architecture), that's it failed hard.

1970s-ish capability systems with support in hardware/firmware include CAP, Flex, System/38, Plessey System 250 (which a former colleague worked on) -- the last two commercial; see https://en.wikipedia.org/wiki/Capability-based_security.

I'd like to think their time has come, given vulnerabilities I see.
