2. Both EM and GR are 1/r^2 interactions.

Isn't this just geometry together with massless exchange particles?

GR has gravitoelectric and
gravitomagnetic phenomena that are remarkably analogous to EM
phenomena.

Isn't this just a consequence of special relativity?

Regardless of their origins, these known characteristics of GR and EM
are similar. Whether these particular similarities are important clues
to a possible unification or just secondary curiosities remains to be
seen.

No, you completely miss the point. We already know the cause of this
particular similarity, and it is not important in giving us any clues to
a unification.
