[ARC5] ADS-B versus HF SSB ?

[Hubert Miller]

I just read an article in the January 25, 2020 WSJ about the Automatic Dependent Surveillance Broadcast  ( "ADS-B" ). It says that now over 100,000 U.S. aircraft now have this 
January 1 mandated equipment installed. Not all classes of aircraft must carry this. This system uses satellites and ground stations to provide GPS locating to the aircraft itself,
rather than have a ground radar station provide location information. The aircraft - derived information can also be shared with other aircraft.  Over oceans, this allows closing
the spacing of aircraft from 40 - 80 miles to 14  ( nautical ) miles and would seem to make the old 15 minute position reports a thing of the past. 
So I wonder: for civilian aircraft, does this mean the final end of HF communications?
