And a good plan9/9front yt-channel:
Go has had a strong influence from P9-flavoured C; the first Go compiler was derived directly from P9 CC, and it took the route of generating machine code rather than using a bytecode VM; instead opting for near-trivial cross-compilation (again, very much in P9 style). Even the Go CI/CD workers ran on Plan 9 (I don't know if they still do).
Plan 9 has also had a very strong influence on wmii, dwm, and suckless.org in general; the suckless people consider C and rc as the least-sucky programming languages. There are some pretty strong ties/cross-influences between suckless, 9front, cat-v (RIP Uriel), etc.
Meanwhile 9front is de facto the only community seriously dedicated to carrying the torch. It just looks like Inferno/Limbo (despite having actually been deployed in production by Lucent) turned out to be a dead-end after all.
Also even though it started as an anti-Sun/Java project from Bell Labs, it was also taken as an opportunity to fix Plan 9 design errors.
Rob Pike for example, has some quotes on how he thinks it was a mistake not to add automatic memory managemet to Alef, and going back to C replacing Alef.
Inferno's approach to a fully managed userspace with a JIT, something that in modern times ChromeOS and Android is what we have closest to in mainstream computing, is also why there are some Limbo features not yet available in Go, like proper plugins (the current package isn't really it), although maybe one could argue net/rpc is the answer there.
