> And yet the latest football game is broadcast worldwide flawlessly.
I dunno, I've often seen flaws in the broadcast of the latest football game. I think it would be more accurate to say "the latest football game is usually broadcast worldwide with flaws that are within the tolerances viewers are willing to accept", but then, people rarely die because of broadcast glitches in football games, so the tolerances there may be fairly lenient.
Because it's the exact same rehearsed process that's performed for years at a time on hardware and software that is considerably safer than off-the-shelf computer hardware.
