Deep Blue vs. Kasparov (May 1997)
IBM's Deep Blue defeated world chess champion Garry Kasparov in a six-game match, the first time a machine beat a reigning world champion in a match.

The research intern is a defined-task milestone; the leap to a full researcher that generates new approaches is the broader domain where extrapolation gets risky.
