effort.  Why has SSH been so successful, and DNSSEC stumbled so badly?
Short answer to that question alone. (Believe me, I've considered it too.)

SSH is an example of innovation that requires only the end points to cooperate - e.g., like TCP doing congestion control at the edges. In particular, the key exchange in SSH is simplistic...

DNSSEC is a change to the operations at the mythical core of the Internet. DNSSEC won't work until third parties are involved, i.e., the parents (et.al.) of the server are involved, not just the server and client. In particular, the key exchange in DNSSEC has been the sore spot.


Mythical core: in this case, the administration of the root zone, the TLDs, etc., not the routing/transit/peering core.
