To put that number in perspective, drawing just 1% of that down each year and putting in a bank account earning interest would fund 100 engineers on $500k/year indefinitely.
Put another way, does the Linux kernel or the Python language need to be run by a company, or will foundations does these jobs ok?
There are plenty of open source projects that are enormously successful without a single lawyer or project manager in sight.
With the same argument you could probably retire, after all you already earned (years you've been working) * (average salary).
I stand corrected, I would want to face the $400M+ per year existential wobble.
A 2m lump sump at 20 would allow me to live a lifestyle of a 20k/year life, not good enough.
Had I lived that over the last 20 years and saved the rest of the 100k in an 8% return fund then I'd have 4m today and could drawdown a 40k/year life at 1%.
Had I been given a lump sum of 100 times my desired salary though, or 10m, then sure, no need to work.
It's not that silly, because that's a huge amount of money. What do you think the gross expense of building software like this should be? Because this may be the end of the line.
Big numbers without context are not useful outside of taking advantage of people who don't think critically.
