  I guess that is the point though.  ATM lost to IP (well, lost to MPLS).  The point the is that IP is winning, and everything else is either losing or already forgotten.

  Well, collisions were just one aspect of Ethernet.  But half-duplex and full-duplex is still an issue on 802.11, where there is one channel for transmit and receive.

  Well, ISDN protocol types made BRI somewhat complex.  Too much configuration.

  Since there are a least five things that have to be transitioned away from these days, and given that a single technology doesn't solve every problem, this is basically a perpetual requirement.
