If you worked a standard 9 to 5 and took 4 weeks of vacation a year, then you worked ~1920 hours per year.
Bill Gate's self-reported work schedule would give him 3640 hours per year, meaning he worked about double the hours of a "regular person".
Bill Gates in 2018 dollars as of 1999 was worth about $150 billion dollars. Giving him an hourly rate of 2018-USD$1,369,863 per hour over 30 years.
Whatever you, or I, or pretty much anyone else on HN is worth is a rounding error towards 0 of that value.
While it is certainly possible that value goes exponential after that first 40 hours, there's plenty of people on Earth who work far longer hours then that and will never be worth anywhere near as much.
