Reality is that nobody knows what is the long lasting impact of web assembly in our industry in the years (or decades) to come, unless somebody can predict the future. As such, if somebody is passionate about it and gives all their heart and mind to it, I see where they are coming from and I respect their commitment.
To imply that "It is just XYZ" in dismissive tone, well that is quite rude and disrespectful at this point in time.
