I have asked this question every year for a long time. Always nice to
hear how opinions change as time passes.
If the current popular openings like the Ruy, English, French, etc are
sound, why does a powerful computer with its book turned off never find
them? I know, it's supposed to be all about "opening themes". BUT theme
be dammed. If its a good opening the computer should find it. I would
expect a strong computer to find the first ten moves in the most popular
Ruy line without hesitation. Never does it seems. I can only conclude
the sequence of moves is somehow inferior.

Two possibilities: either some other opening is better, according to
the computer's evaluation function or one of the standard openings is
the best by that criterion but it takes an unfeasible amount of search
to find it.

That conclusion is a possibility but not the only one. Even if the
Ruy is inferior according to some computer's evaluation function, it
probably isn't far behind the `best'. Who cares about a couple of
centipawns? Even a tenth of a pawn?

The computer excels at tactics, and there usually aren't any forced that
early. What you're seeing is a weakness of the computer program, not the
opening.
