We compare hydro simulations of Cold, Warm and Wave Dark Matter with new microlensing and galaxy formation data from JWST. Our pioneering simulations of a bosonic condensate with de Broglie scale waves on astronomical scales (aka the Axiverse) shows the unique soliton ground state may be responsible for the Little Red Dot galaxies discovered with JWST and how they may evolve by wave action over the Hubble time to resemble the puzzling Ultra Diffuse Galaxies and their globular cluster populations mapped locally with Euclid. We conclude that the old metal poor populations of globular clusters in general may originate by this inside out mode of Wave Dark Matter.
