Things that were once thought bricked might in the future become unbricked if the right knowledge is acquired. "Bricked" is more a state of "thought to be impossible to fix" than something permanent.
That makes sense, especially since there is an epistemological issue with being able to say something is 'bricked'... there would be no way to distinguish between "I don't know how to fix it" and "No one knows how to fix it"
