The WASM cliff is very real. Every time I go to use it, because of the complexity of the tool chain and process of going from zero to anything at all, I feel like I'm already paying a cognitive tax. I worry that I should update my tooling, look into the latest and greatest, understand the tooling better, etc... It would be incredible to see that improved.

The difference in perf without glue is crazy. But not surprising at all. This is one of the things I almost always warn people about, because it's such a glaring foot gun when trying to do cool stuff with WASM.

The thing with components that might be addressed (maybe I missed it) is how we'd avoid introducing new complexity with them. Looking through the various examples of implementing them with different languages, I get a little spooked by how messy I can see this becoming. Given that these are early days and there's no clearly defined standard, I guess it's fair that things aren't tightened up yet.

The go example (https://component-model.bytecodealliance.org/language-suppor...) is kind of insane once you generate the files. For the consumer the experience should be better, but as a component developer, I'd hope the tooling and outputs were eventually far easier to reason about. And this is a happy path, without any kind of DOM glue or interaction with Web APIs. How complex will that get?

I suppose I could sum up the concern as shifting complexity rather than eliminating it.
