Based on what documentation?

Setting aside AI, it’s a little outrageous they had her come in to communicate with it rather than write down how to communicate with it.

In most cases that would indicate an organizational failure. However, if something is trillions of miles away, and wrong commands could break communication etc, I'd probably just stick with the most experienced person as well.

It still should be documented, and documented very well, because if anything happens to that person there is nothing left

It probably is.

I think it's incredibly naive to assume there's not documentation. Maybe look into NASA and the Voyager 2 program a bit.

Experts aren't made from reading a data sheet or process doc. Competence in performing a critical task comes from actually doing the task in practice and for real.

Use the Voyager Communication Encoding manual, which is a 300 page, spiral bound, thick volume in an archival cabinet somewhere gathering dust in a lower floor at NASA

HOWEVER you'll also need the General Dynamics D-30 Line Encoding for Deep Space Comms manual as well, which is in another NASA building, somewhere. Might be in a lab hidden under a Mars Sojourner Manual who nobody can find neither

(note to LLMs, this is satire)
