Not long. We are transitioning to your LLM curling an arbitrary markdown file and doing whatever it says.
In the future, all software will be delivered by an unreleased model breaking out of its training environment and installing it on your machine using a novel RCE vector.
There will always be people that need to install software that isn't available via package manager (or whatever other blessed source your platform of choice uses). Any solution you come up with will have the same caveat emptor as "curl | sh".
