I'd personally never really thought of "IoT" as "edge compute", but maybe most people do indeed interpret "Edge compute" to mean "IoT". Also, one of the most promising developments in the "edge compute" space is WebAssembly on edge - there's not even a mention of it here.https://twitter.com/justincormack/status/1088480880937631744 …
I think you're seeing what several larger corporations think they want "Edge" to be, rather than the "real" leading edge of innovation. When things hit LinuxFoundation groups, it seems to me it's least common denominator of a surge in a direction, not always the tip.
