I've heard of webassembly replacing containerization before. As an avid abuser of gitlab-runner: does this mean I'll eventually be able to run my pipelines usin

  Your pipeline processes would be compiled to wasm, and any syscalls they make would be serviced by the wasm runtime, which can apply whatever restrictions it wants to to contain what the process can do. If your pipeline processes are not compiled to wasm, they could alternatively be run on an ELF loader + interpreter that is compiled to wasm and functions just like in the previous paragraph. Of course that'd likely be slow, just like running CI for a foreign arch in qemu is slow.

    That does sound promising. It makes me wonder why, though? What does WASM do that containers don't? edit: actually no, I answered my own question in my head: I can think of some applications for WASM that docker simply can't handle at the moment. ledger-cli, for one. I've wanted to include that in a flutter application for almost two years now. WASM seems like the perfect candidate to take care of this.
