The post carefully avoids making any more expansive claims than "I tried to use WASM in the most obvious way apparent to me and ran into a lot of difficulties".

The post carefully avoids making any more expansive claims than "I tried to use WASM in the most obvious way apparent to me and ran into a lot of difficulties". What this implies for the grandiose claims of some WASM boosters is left to the reader to determine. (And I'd describe myself as fairly pro-WASM myself.) In that sense it's a great counterbalance to the hundreds of "here's how I used WASM to accomplish some trivial or meaningless task" pieces you see out there.
