Why is it not recommended to shut down a computer "brutally" (power switch)?

It is now in the general knowledge that one should not shut down a computer using its power switch. But why is that exactly? Is it a myth that stuck from past architectures?


Is it solely to prevent corruption of data that's being written at the time of shutting down (bonus: how can it be corrupted exactly?)? I'm pretty sure hard drives' reading tips don't crash on the disk anymore when powered down (or I would be out of HDDs by now).


More precisely, does power cycling a computer with its power switch makes it wear out quicker or even become damaged in any way, and why (hardware only)?
