The important part in my eyes are signed packages. Curl on a random website is too dangerous for my taste. Sure, a signature does not mean the software is not malicious. But it at least is a proof of that it comes from who it claims to come.
Curl on a random URL without signature check is a recipe for trouble.
Try to figure out how your package manager installs missing drivers - One of the things which Microsoft screwed up on Microsoft Store and MSIX packages. You literally can't touch PowerShell to install INF driver using PnP utility. You have to have executable installer.
But configuring / setting up complex pieces of technology is something in which I let LLMs help me regularly. I'm happy that I don't have to RTFM that much anymore to get something done. And yes, I'd hate to figure out IAM policies myself or decipher a truckload of error message of third-party systems by myself.
So, yes, I expect LLM help with these kind of things is going to become the norm.
For an LLM to work well, the installer should still exist, the UX should also be kind of self-explanatory and the error message must also have relevant and clear info.
So in that regard, not much has changed.
