> I think the problem is calculating pi must be done in series, so you can't really get much further than anyone else. contrast that to a hypothetical situation where you could effortlessly start calculating at the nth position of pi. There is this: https://en.m.wikipedia.org/wiki/Bailey%E2%80%93Borwein%E2%80%93Plouffe_formula https://en.m.wikipedia.org/wiki/Bailey%E2%80%93Borwein%E2%80... , so you can calculate later digits of pi without the earlier ones.
