Anyone that's been in tech at the FAANG tier for two decades and doesn't have at least one to two years of runway not including retirement accounts is observably terrible at managing money.
Most small shop tech jobs in smaller cities pay very little comparatively. The OP said they were currently at FAANG, not that they have been at that level for 2 decades. Having worked with lots of people with over 20 years experience, a lot of them stuck with a single company their entire career and are making nowhere near FAANG.
There is not a day since then that I have lost sleep about losing my job. I’ve always found jobs quickly.
My expenses starting next year should be lower than they were when I was making less than half as much in 2016. I’m voluntarily helping my younger son out in some ways until he turns 22
