Sooner or later we will be "useless"

Sooner or later we will all be "useless"

It seems to me just stuff to entertain the audience and the orchestra.

Wait a moment!

It is one thing to raise your hands in time, turning and emphasizing the orchestral part that is most important at that moment of the musical work, and it is another thing entirely to be those infinite rehearsals where a conductor tries to convey their vision of the opera to the orchestra and how it must consequently be performed.

Now, a robot might also perfectly mimic a conductor during a performance, but I see it as very difficult to give directions during rehearsals, stopping the orchestra, saying "this is fine here and not there," restarting from such-and-such a point, etc., etc.

Here, they will never be replaceable.
