Firewalls, air gaps, and authentication are still quite effective. Having a person who authenticates through those on your behalf, and exfiltrates information by hand, is still valuable. Not to mention the information and work that is intentionally kept in-person. To see the value of spying, see two recent news cycles: The 21-year-old National Guardsman who leaked a bunch of sensitive info for forum cred (thereby causing a lot of headaches for the U.S. presidential administration). Just imagine that info going to a foreign govt instead. The court case in which Google got admonished for taking any sensitive info off of chat, and auto deleting history. A spy in those offline conversations could still report on what was said.
