> The spiritual successor to Flash <...> is probably more WebAssembly than HTML5
The author's point is that Flash had GUI authoring tools and was "content-first", whereas js and infinitely more so webassembly are programmer-first. It doesn't bother me a bit (am a programmer), but it does bother him.
I wonder how long it will be until there are content authoring tools that build to WebAssembly? For a long time, Flash was kind of the runtime for stuff you couldn't do in the browser with HTML + JS.
