DESI is just one of the super-mapping scopes to come online in late 2010s-early 2020s. There GAIA about 3/4 through its program to map the positions and movement of 2 billion stars (2%) in the Milky Way. And the Roman telescope will rephotograph much of sky at least once a week, looking objects that change brightness or position- about 10,000,000 expected a night. These could be new asteroids, Planet X, super novea, etc.
