Here’s the point of the whole thing. The IETF people, when they were thinking about IPv6, saw this mess getting made - and maybe predicted some of the additional mess that would happen, though I doubt they could have predicted SDN and wifi repeater modes - and they said, hey wait a minute, stop right there. We don’t need any of this crap! What if instead the world worked like this?
The FIRE (Financial Independence, Retire Early) movement is a lifestyle movement whose goal is financial independence and retiring early. The model became particularly popular among millennials in the 2010s, gaining traction through online communities via information shared in blogs, podcasts, and online discussion forums.
Those seeking to attain FIRE intentionally maximize their savings rate by finding ways to increase income or decrease expenses. The objective is to accumulate assets until the resulting passive income provides enough money for living expenses in perpetuity. Many proponents of the FIRE movement suggest the 4% rule as a guide, thus setting a goal of at least 25 times estimated annual living expenses. Upon reaching financial independence, paid work becomes optional, allowing for retirement from traditional work decades earlier than the standard retirement age.
Another type of American Dream has now developed: The freedom to upturn your desk, give your boss the finger, and retire on the spot—without making a lifestyle sacrifice, of course.
In some circles, the wealth required to burn any bridge you want has a name: “f–k you money.” That’s because, well, backed by the First Amendment and a large fortune, you can yell that without consequences to pretty much anyone, save for a judge, a plumber, or a tax assessor.
I decided then to write up the practices that I think lift a newly minted software engineer from amateur to professional: the path from fixing bugs as an “Engineer 1” to leading major projects as a “Senior Engineer.”
