I'm really glad my first (part time) job as a fresh-out-of-highschool 17 year old required me to call about 5-6 companies/people per workday. A good number of whom where existing business relations, so not a whole lot of room to fuck up.
First week was really anxiety-inducing, because I HATED making phone calls.
After that, no issue. Today, I'd 1000% rather call a doctor's office, restaurant, plumber,... Than write an email. Online forms are fine, but phone calls are just better. You can get the back and forth often needed for planning done in like 5 seconds.
Lost me at LLMs. My Nix config is over 20k lines long at this point, neatly split into more than a hundred modules and managing 8 physical machines and 30+ VMs. I love it.
But every time I've tried to use an LLM for nix, it has failed spectacularly.
