I wouldn’t call it an “Attack” on FIRE. I love a lot of what the FIRE movement is about. The math behind the FIRE movement is flawed though. The 25 times/4% rule was designed to sustain a 30 year retirement.
Eventually, my goal will be to cover living expenses purely with financial capital, but if I were to start living fully off my financial capital at 32 I would need a lot more than 25 times my expenses saved up. So, my focus right now is on expanding my income from doing things I love, while still saving money for future FIRE.
