We've long since offshored the development of any physical products that isn't considered ITAR/defense world.
At my previous workplace I wrote a documentation bot which helps people find documentation based on vague descriptions of what they are looking for (like when you know you saw something but you don't know where exactly or what the keyword is). Or by specifying what you want to accomplish.
Mind, the bot would not create answers to questions, it would just ingest existing documentation and point people to things that are relevant to their searches.
Hmmm, wonder what I've been hallucinating about for the last 30 years.
