It took the Triarii 10,000 years to regain modern day tech from Stone age tech, which took humans hundreds of thousands of years, I don't think they are too interested in decoding and would rather just replace it with their new gizmos... But I'd be very surprised if you needed to decode it anyway, I thought we would keep our languages...
