Networking and distributed software are well understood nowadays, the lower productivity of web companies vs. SpaceX etc. comes from all the unstable (both ever-changing and buggy) software they need to use. Most modern software is affected by this, but the web has it worse because of security issues and because the way browsers are evolving (on purpose, one has to add, because it's a cartel of large players on the web trying to stifle competition). SpaceX doesn't get some innovative new alloy they didn't order every couple of weeks and even the games industry has fewer obstructing external dependencies (hardware vendors and their drivers being one). At least that's my experience from about 20 years of web development (15 professionally).
