I don't think anyone can consider it a success just yet. But someone just injected 2 billion dollars into the enterprise. They are probably given a lot more information than you and I are. Maybe those people are dead wrong and they lose all their money, but maybe not.
With the public information there is neither a point in positivity not negativity. It would be speculation either way. A question that could be worth pondering is what exactly the investors are shown? What would you need to see to put all your money in thinking machines?
