Kind of ironic that the video makes a compelling argument why such arguments are wastes of energy and miss the point. For those who don't care to watch, the tl;dr is Euler used the constant symbol for pi similar to our use of theta, as a constant without a fixed value. Sometimes it was 3.14, sometimes 6.28 and sometimes pi/2, just depending on what problem he was solving and what form was most convenient. The lesson being, don't get caught up wasting energy on the argument that could be used towards solving problems.
