Aren't they historically unconnected, as the quote alludes to? 1's origin is in counting. pi's origin is in the study of the circle. 0's origin is in accounting. i's origin is polynomial algebra. e's origin is in the study of exponentials and derivatives. The relationships between all of these fields is a discovery in itself, and a revelation that was not apparent at all throughout history, and it is still not apparent to most people who haven't studied math in-depth. Basically, e^ipi + 1 = 0 is proof of the connection, one that is not at all immediately apparent, and has not been known for the majority of humanity's history.
