Go has been played long enough, and the proposed "great wall" opening is
simple enough, that is should be more than valid to argue that "if it
was a good opening, it would be played more often".
Here are some openings that have been found to lead to high winning
percentages in real games:
- The Shusaku opening in the old pre-komi days
- The Chinese opening (still holds one of the highest winning
percentages with Black, of all openings, if I remember correctly)
- Mini-chinese
- Kobayashi opening
One could try and plonk down those openings and see whether the engine
has a significantly better result. I would conjecture that current
engines are not strong enough to use them correctly, and it won't make
any difference where you place the first three stones, as long as it's
reasonable distributed and not on the second line.
I may extend my conjecture to amateur players under about 3 kyu :)

Not really a compuetr Go issue, but I do not think that great wall is
superior even when completed. It is not too bad but it needs a
definite strategy from wall owner. I.e building side moyos using wall
as a roof and hoping that the other guy gets nervous and jumps in. So
by being patient is pretty good defence against it.
Even when completed I think it's inferior. But that doesn't mean you
can take it lightly. There's a psychological component to it that
makes it easy for the opponent to make a mistake. Also, White may have
some advantage by having more experience with the strategy.
But I agree with the pro that if you disrupt it by preventing
completion with the last move it really turns disadvantageous for Black.
