Digital art 'perhaps' causes artists to decline in certain abilities, such as the ability to mix colors by hand, pen control skills, etc. In terms of these operational technical aspects, digital artists generally really can't match traditional artists. An artist who specializes in digital art but never paints with oils may indeed be inferior to traditional art masters of the past in certain fundamentals.
Because of convenient layers, masks and Ctrl+Z, as well as mirroring, zooming the canvas, layer modes, filters and other convenient functions, what digital artists need to consider is no longer problems at the operational technical level.
But whether it's digital art or traditional art, I think judging whether a work is good or not ultimately depends on looking at the finished product rather than the process (although I do really enjoy that process, but that's the artist's personal matter).
No matter what method you use to create, good work is good, so I don't think digital art makes us worse artists.
The emergence of digital art has greatly increased the possibilities of art, but the uniqueness of traditional art means its value will never decline.
Of course, if you ask me which I prefer, I would say I like traditional art more, even though I haven't drawn it for several years XD. The brush strokes produced when drawing by hand are truly fascinating to me. Although many software programs, especially Procreate, can also achieve amazing brush stroke effects, they still can't match the feeling of drawing on paper.
