If that is happening to you, you should DEFINITELY be replacing it with better stuff. That doesn't mean your fluid has 'gone bad' though, that means you drive like a lunatic.
This is something that 99.9% of drivers will NEVER experience. It takes some serious braking to do that to a car. If you are driving fast enough to require braking to that extent, you should be arrested.

Fresh sealed brake fluid has a boiling point between 400 to 500 degrees. After the sealed can is opened the fluid continues to absorb moisture and the boiling point will fall. After a couple years use, the boiling point can be well over 100 degrees less than fresh brake fluid. You don't have to "drive like a lunatic" to boil the fluid, one trip to the mountains could do it.
PS The chance of boiling is not the only reason to change the brake fluid regularly. The accumulated moisture also rusts the brake system from the inside out. Regular brake fluid changes are rather cheap compared to repair costs on modern ABS brake systems.
