The cure for my 5 month old MBP being bricked by Big Sur?
Apple replaced the Touch ID board and the main Logic Board (which holds the CPU, RAM and storage)... basically... they replaced all the bits that matter in a computer.
They once replaced the screen, keyboard, trackpad, battery, top and bottom case, power jack board and logic board on mine. For free as part of the graphics card warranty extension.
I think the SSD and the speakers were the only parts left.
