I'm sorry if I sound rude, but I wanted to have a bit more of a
substantive discussion than quoting the man pages.  Especially since
what you are quoting dates back to a change to
src/crypto/openssh/ssh-keygen.1 dated the following:

Being that the old "considered sufficient" of 1024 was added at the
following revision date:

I would say that we are exactly due for a real discussion as to what

GPUs.
