On the surface it sounds like 'hmm sure why not' then you stop and think about it. It is a security/privacy nightmare waiting to happen. Much like ActiveX and java apps were. I suspect webassembly will end up in the same place. Frankly it will be used by some small segment of web applications that are cool like you say. At best I fear the majority of the use would be just to fingerprint us more to show us more soap/shoes/drugs to buy. At worst it would end up being a never ending pit of security vulins. We have tried this sort of tech before it worked badly in the end. So a bit of caution is not unwarranted.
