According to Peter Bright at ARS:
New cloud-imprisoned Lightroom has 1TB of photo storage, same UI across desktop and mobile
You can read it yourself, but I'll pull out the best bits (further emphasis mine):
For the time being, the desktop-based Lightroom Classic will continue to be developed.
The current Lightroom CC is being renamed to Lightroom Classic CC, and a new product with an old name, Lightroom CC, will take its place.
The new Lightroom CC offers most of the photo processing features of Lightroom Classic
"likely" contentious feature: it uploads *ALL* your photos to cloud storage.
Adobe is using that cloud storage to perform object detection (and more!) on your pictures
