I think maybe that was implied, considering the topic of conversation and website we’re on.

That said if you’re making $250k+ a year and not on track to retire by 50, seriously please open a retirement calculator and figure out what you need to do to get there.

A majority of software engineers don't make enough money to retire at 50. People who have retired so young tend to be very lucky in both employment and their investments. Most probably stayed unmarried, inherited significant amounts of money, and/or married into even more money. It also helps to be lucky enough to start with a $100k+ job at age 23 and never have any bad luck to set you back. I've met people who check some/all of these boxes, and even they seem to not be retiring at 50.

When you can retire depends on how little you need.

Though, of course, if you're living from investment income you should be aware you're living off the work of other people.

This. People act like we’ve gotten $200k+ for more than a decade. Most of us haven’t. It wasn’t until 10 year into my career that I hit $100k so this is boomer math that doesn’t account for inflation of everything.
