Everyone make their own artistic judgements, nobody's ideas are better. If people prefer this https://lexica.art/ (scroll down) then that's their right.
I imagine there are plenty of people that prefer Autotune voices for some reason too. Doesn't mean everyone needs to agree that it's good in itself or for artists.
And it's not a new phenomenon. The printing press made scribes nearly obsolete, cars led to a mass slaughter of horses (and all related professions), and so on wherever you look. Invention of photography nearly killed whole genres of art (and gave rise to impressionism, abstractionism etc.)
Unfortunately, we can only judge the outcome of these changes only decades (or even centuries) after they happen.
I'm personally not against the idea of "AI as a tool to help." I just think with art, and the way the AI art software works, it's not a helping tool; aside playing around with it for fun, it's a "quick riches" type tool, more like faux leather/Pleather/PU leather.
The important question being, why would you pay for these tools? All I've seen are articles around how well they can create art 'in the style of X' as the exciting bit.
