Torontonian here. I understand your concern, but my opinion is that its a worthwhile (contained) experiment in a space (urbanism) that could use some new information about approaches that work and don't work. In the hypothetical case you describe where Google decides to drop it - a case I find unlikely to be done as suddenly as you proposed if for nothing else but bad publicity - I could see the neighbourhood becoming a normal neighbourhood of Toronto with perhaps a cool extra things added. Currently it's essentially a dead industrial land in a great location that has been underused for too long, so the opportunity cost does not seem so high.
