Doesn’t matter. In five years the world will be awash in encryption they can’t break.
It already is. The only reason this encryption is "breakable" is a poor choice for a portion of the key.
A 4-digit passcode is easily breakable via brute force. Even a 6-digit code is breakable, if you can try it often enough.
The only reason fingerprints are insecure is the current precedent in US courts, that say a fingerprint is evidence, rather than self-incrimination.
It already is. Last count: over 880 free and paid apps that can completely encrypt data on the flash drive (although not as completely as Apple's wall-to-wall system), to a 256 bit AES standard.
That will be the end of the Fifth Amendment or of the law.
However if mass market manufacturers offer encryption - at a reasonable price- that allows legal access only criminals will turn to Apple’s high-profit encryption paradigm.
I can’t imagine what country Apple thinks doesn’t want it’s courts to function.
