The 1984 version of ASN.1 should die, but the 2008 version is widely being used in many industries. Digital Certificates still use it. Air-to-ground communication uses it. Financial services are using it. LTE (the next generation of mobile telephony) uses it. Electric Utilities are using it in monitoring power lines. Toll Roads are using it for those electronic payments so that you don't have to stop at toll booths. Incident Management - Fire, Ambulance, Police, Trafic Control, etc - use ASN.1. I could go on naming other areas as well. The 2008 Edition of ASN.1 is definitely NOT dying!!
