The Ultimate Demographic Study

So, just how many people HAVE walked the earth? How many humans? Ever?

At least 20 years ago, I first heard the opinion expressed that there are as many, or more, people ALIVE now than who have ever lived and died. That always sounded incomprehensible to me on its surface -- but what ARE the relevant numbers? This article reports on a demographer who has tried to quantify this.
