Let me suggest that the meaning will require working effectively with concepts. That is, humans, who actually have real intelligence, can read words and identify and work with the underlying concepts, but apparently so far no one knows how to program a computer to do this.

The parsers available are good enough for English. Sadly, that's absolutely not true for other languages.

As a French with a strong accent, Siri probably understands only half of what I say and I have to make lots of efforts.

So you are saying, all we need is true AI to fix our parsing problems? Well then, all is clear and easy now ...

(How else would the computer understand "meaning" without beeing strong AI)

Sort of, more like, "our parsing is good enough for our use cases, we'd make more progress if we focused instead on getting closer to true AI"

We don't even need true understanding of meaning, even a lousy approximation would be an improvement at this point (or I should say, a slightly less lousy approximation compared to what we have now).
