I assume you mean this as a moral claim and I can agree in that case. However, it's meaningless of course and kind of infuriating in any other light, because this is the world everyone has been mindlessly begging for and there is no chance that it comes without extremely severe consequences. An automated world like this means even less power for working people than ever before, so how on Earth do you expect to realize any of these desires? Do you still think capitalists care about your privacy? Even if they did "care" it wouldn't matter because they have to compete.
