That's the counter argument - humanity is still here. Calculators didn't destroy it, and the economy is still prospering despite them!

But society isn't. And no, that's not the calculators fault. It's one little thing among the many that make us too comfortable and restrict us from thinking things through. From having that experience, that challenge, that blockade we need to get through. Life as surviving is getting easier and easier, thanks to technology. For some, that is necessary still. But for others, who live in over-developed countries, it's slowly destroying life.
