According to some people... The sum of alternating +1 and -1 equals 1 if you stop on an odd, and 0 if you stop on an even. Infinity is treated differently in different fields. I suppose in physics, it's probably treated as a superposition of even and odd, so statistically, you could interpret it as 0.5. And I'm sure that works great for physicists and it fits a number of scientific models. But there are probably other fields involving mathematics that would find this interpretation to be silly and not very useful.
