Wasm has different characteristics than docker containers and as a result can target different use cases and situations. For example, Imagine needing plugins for game mods or an actor system, where you need hundreds of them or thousands, with low latency startup times and low memory footprints and low overheads. This is something you can do sanely with wasm but not with containers. So containers are great for lots of things but not every conceivable thing, there’s still a place for wasm.
yeah, I mostly see it competing with Lua and small function execution in a safe sandbox (e.g. similar scope as eBPF). and maybe for locking down problematic stuff that isn't ultra performance sensitive, like many drivers.
so agreed, plugins. in games or in the kernel.
