6 months worth of living expenses in 2025 is gonna be, median, $10k in rent/mortgage payments alone. That in and of itself is like 14% of someones annual income at $35 an hour.
I truly fail to see how 20% saved annually isnt something reasonable, considering the need for different draws out of some of it will come sporadically, while you also need to be saving for your retirement in some inevitably inflated future where everything is even more ridiculously expensive than it is now.
The first describes a total emergency fund of 14% annual income that would provide 6 months rent. The second describes annual contributions of 20%, which seems like it provides 6 months living expenses for every year worked. That's an awesome goal, and kudos to anyone who can do it. I did. It let me retire at 45, which is several steps beyond "living comfortably."
