Lawrence, any guesses as to what Dark Matter could be? Nobody
can find any evidence of WIMPS and now sterile neutrinos seems to
have bit the dust. Would you bet your money on Axions, or some
modification of General Relativity (teleparallel gravity perhaps)
or none of the above?

I have no commitment to any particular theory. Dark matter might turn
out to be some new physics involving mass-energy in an entirely
different form from what we traditionally know as particles or fields.
Dark energy is most likely some sort of vacuum energy, where the big
unknown is how the vacuum energy is so small compared to what QFT
predicts.
I liked Vic's idea that the holographic principle suggests that the QFT
prediction is just overcounting the degrees of freedom.
