Being perfectly frank: this really resonated with me. I fought through all this about 18 months ago and it was worth it. Tried again 3 months ago and it was impossible, gave it a solid 3-5 days before I pulled back and just did FFI on native and JS on web.
WASM has an extremely high learning curve and this post did a great job representing it. Even the "oh you just need X Y and Z" post is indecipherable to me and I learned the acronyms, again, just 3 months ago.
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.
