Why are we running this stuff at the edge anyway? Wasn't the point of the web to permit light/thin clients? What problem is this really solving? I feel a lot of these new methods exist simply out of "holy crap look what we can do" factors. I have a hard time thinking that running a PHP interpreter in WASM on a smartphone is a smart idea.
