No
I suspect that the human gambled about 29.Rg6 without checking all the
possibilities with the idea that if he cannot find a defence for black by some
selective lines that he analyzed then the opponent will probably also not find
it even if the sacrifice is not correct.
In this case the sacrifice seems to be correct but there are a lot of cases when
humans sacrifice wrong sacrifices for the same reason.
I also will never bet that no computer in the world can find it in comperable
time(it is easy to say that no program can find something and proving it is
clearly impossible task when you do not have all the private programs to check).
I do not have chess system tal but I will be surprised if no program can find
it.
Some possible line based on Ruffian's suggestion is the following line and I
guess that most programs need time even only to find 4.Rh7 with a positive
score:
[Event "?"]
[Site "?"]
[Date "?"]
[Round "-"]
[White "?"]
[Black "?"]
[Result "*"]
