Well, it may consume the AI environment. Maybe even the internet. It's not going to consume a PC with g++, though (at least if the PC doesn't update g++ any more once g++ starts accepting AI contributions).
There may come a point where having a "survivor machine" with auto-update turned off may be a really good idea.
I already do this, in the form of survivor machines made to do initial coding on a retro platform so the result will translate across all possible platforms. Got to, as I'm an Apple coder primarily, so if I want to target older machines I can only do it through a survivor machine: support is always pruned out of Xcode and it would be insane to try and patch it to keep everything in scope.
