Wasm is not only for browsers. There is wasmer, for example. The author is saying that you will be able to replace docker (I think comparing to kubernetes is wrong) with wasm, because it can run code sandboxed. Another example is a plugin ecosystem using wasm. Your go program would be able to load plugins written in c, lua or any other language that compiles to wasm.
