Fascinating.

They mention in the paper that the Dark Ages power spectrum would require a 100,000 dipole antenna array, seems like we are far from that.

Full disclosure brain fart - dark side of the moon still gets sun light (duh, right?), this basic fact had me scratching my head with regards to power source for an embarrassing amount of time.

One of two components of phase 1 implementation of the SKA[1], the SKA1-LOW in Australia, will host around 130,000 dipole antennas[2] when finished with construction starting soon.

Some scientists prefer the term Far Side because of this :)
