For human go players, pattern matching is an excuse to delay neceassary reading. Almost exactly the same two shapes can have fundamentally different behaviour.
I agree with what you said, but not with the implied conclusion.
I think the only interesting or "game" part of go, I mean the part that is suitable for intelligent beings, is the extent where reading (search/minimaxing) can be substituted by other methods. Minimaxing is a simple task that does not need intelligence. I see tasks of pure minimaxing more like programming challenges, and I think most players who pick go over chess do so for this non-reading part.

We can make a clear distinction between two aspects of evaluation. One is knowing which side is ahead, and the other is knowing what the next move should be.
Monte Carlo only (at least directly) tells us who is ahead. My guess is that it's generally better than humans in the endgame (even if an exception may be made for the last few points). It may or may not match humans earlier in the game
I think you overestimate MC in itself. A program does not need an evaluation function better than humans. Even a slightly weaker evaluation can make a killer player (since it will be applied at later nodes) when paired with the computers' superior search (which OTOH relies heavily on the other kind of evaluation mentioned). And search will always remain the computers' biggest strength - and in the long run, superior to all other (strategic) approaches. But since humans cannot aim to calculate THE real solution, it's still interesting to compete with other methods.

As regards knowing what the next move should be, humans may actually be better than machines on average, but they also make more fatal mistakes (that seems to be the chess experience).
I agree, this is another example of the search <> knowledge opposition mentioned above. Again a slightly weaker evaluation can be sufficient when paired with better search.
