gollark: As far as I'm aware, quantum stuff can mostly just accelerate specific algorithms and will be relegated to expensive coprocessors like GPUs.
gollark: Why not just get ahead of the problems and use 128-bit ints?
gollark: When using sane non-JS stuff I try to use 64-bit timestamps so they'll be valid for 584 million years.
gollark: They'll probably begin to break a bit beforehand, due to inaccurate clocks and computing timestamps a bit in the future for various purposes.
gollark: At least JS isn't C, I suppose.
