Observations are being ruined now. Those cheap space telescopes will be available when ecactly? Is there even any project in the works besides JWT? Projects like these take a lot of time.

Improve observation data post processing. Lasers are used as artificial stars [1] to subtract atmospheric distortion, use stacking [2] to remove StarLink tracks. Those observations aren't being "ruined", they simply have some noise to remove.

Long term, we should be lifting observatories (both optical and RF) into orbit, Lagrange points, or the Moon. Observing from the ground sucks comparatively, and there's a lot of space out there.

That might work for imaging, but what's your fix for spectroscopy?

Optical, RF, or Xray?

Let's start with optical.

Yes WFIRST[0] is currently in the works.

JPLRMA[1] is investigating low cost mirror for space observation although they are primarily focused on the outer planets of our solar system.
