With a small, but quite relevant MAX-Photoshop Sneak Peek, Adobe is taking the floor. The upcoming Object Selection Tool has it all and defines the current state of the art for an AI-based selection in Photoshop until further notice.
The small, published video demo shows how to roughly enclose objects in an image either with a box or with the lasso tool.
Then the (hopefully correct) detected object is selected or masked with edge precision. This is made possible by object recognition using artificial intelligence, which at Adobe has the brand name Sensei.
Similar algorithms have been known for some time, but these models have to be trained for daily use with a lot of relevant data. One can assume that Adobe was able to use a lot of image material as a suitable training input, especially since the company has its own image database with Adobe Stock.
By the way, the new feature is no longer a technology study. At the end of the video Adobe promises that the new Object Selection Tool will be available "soon" in Photoshop.
