This is music to a techie’s ears.

On Tuesday night, a robot conducted the the Lucca Philharmonic orchestra in Pisa, Italy. The two-armed, human-like robot, named YuMi, conducted three musical pieces, including La Donna e’ Mobile, a renowned aria from Verdi’s opera, Rigoletto. But conductors shouldn’t get freaked out yet. The robot is still not able to improvise, so as Reuters notes “any unexpected change in tempo from the musicians would have been ruinous.”

While this robot isn’t in a spot to take a conductor’s job, that could change in the future for this and many other jobs. Indeed, almost half of the jobs in America are at risk of being done by robots or computers in the next two decades, a study by researchers at Oxford University found.

And there are some jobs that robots already do that may surprise you. Here are eight.

Robot solidiers can dismantle bombs, shoot guns and more. By one estimate, robots will replace about one-fourth of U.S. combat soldiers by 2030.
