No, I wouldn't go so far as to say he thought it proved anything. What
he showed is that IF the principle of locality held (which he believed
it did), THEN there would be a problem. We'll never know what Einstein
would have said after the results of the Aspect experiments, but you
can rest assured that Einstein, like all physicists, recognized that
experiment has the final say in all such matters.

Einstein isn't here to defend himself about his intentions or
predispositions about theory vs. experiment, and I don't think there's
much point in attempting to read the minds of dead men.

So, let's just focus on what physicists think of his work and what
value it has and for what.
