>(Confusingly enough, with typical “machine precision” computer arithmetic, this doesn’t work correctly, because even though one “runs out of precision”, the IEEE Floating Point standard says to keep on delivering digits, even though they are completely wrong. Arbitrary precision in the Wolfram Language gets it right.)
The man can't help but promote himself. He worded this in a way that makes it look to a lay person like he invented arbitrary precision arithmetic, but in a way that is still technically correct. It's like he's actively trying to peddle something to people who don't know any better.
