oh from the technical side, my intuition tells me that this is not a successor (flash, java activex) but a very efficient virtual machine that can replace docker and work close to the user because of the size of the application, its predictability in operation. The problem seems to me that another one is that the performance of WASM is also one curse, because it is not at all easy with the fact that it runs everywhere the same (code) instructions almost like for the CPU, the portability of it seems to me to be limited, and as for any virtual machine, security is a taboo subject.
