Beauty DC-X is irrelevant as it never even made it to space i.e. crossed the
Von Karman altitude. IIRC.

I seem to remember a discussion on AR years ago about recovering
rocket stages whereby the engines would serve as heatshields by
circulating liquids through their cooling channels during descent. But
never by powered descent plus landing, an option Falcons demonstrated to
All comments at that time on powered reentry were
poppycock/negative/laughing stock entries ... why such common
shortsightedness then?
I do not think the powered and chute less VTVL reentry option was
invented by Musk & team. Then who invented it? NASA people? Was there
a patent about the issue on which SpaceX based further development
into the Falcons reality?
Rupert Sheldrake's theory applicable?

Probably not much farther than they are now, given that the help to
SpaceX was hundreds of millions to produce flying rockets with flying
capsules on top, while Skylon development is still forecast to cost
tens of billions and there is no plan for a less-expensive
demonstrator first. (Which puts Skylon in the "need not be taken
seriously" category, in my opinion, since nobody is going to spend
that kind of money on an unproven concept.)
