I don't understand the desire (fetish?) for high speed home Internet connections at home. I have 25 Mbps up. 10 Mbps down. Have had it for years. It's fine. It's fine when both my wife and I are working from home and doing calls. It's fine for software development. It's fine for email and web browsing, and everything other than downloading maddeningly large files, 99% of which shouldn't be that large anyway. It's fin…
Honestly, most people go for the shiniest number they can afford.
But I will say that as a software developer who has had to fix bugs on random branches of very substantial software projects (web browsers), there is a tradeoff between recompiling the whole project and simply downloading the binaries that the CI system has already built. When I had to jump six months or a year into the past to test some old build, gigabit service was the difference between a few minutes to download the binaries and 20–30 minutes to recompile them myself.
But these days 100Mbps is really more than enough.
An interesting technology that might become a killer app in a year or two is 4D gaussian splats. This is a way of creating photo–realistic animated 3D scenes that the user can move around in, viewing them from all angles (without any need for artists to build geometry or paint textures). Right now streaming them in real time needs about 500Mbps. I’m sure that a few years of iteration on compression techniques will lower it significantly, but it’ll always be more expensive than mere 2D images (even animated 2D images). For reference, most streaming services use about 15–25Mbps for a 4K television stream.
