This is a pretty complex topic, as a quick knee jerk I agree AI art isn't art in the common sense, but one thing I disagree with is that all art has intent or even needs it.

I don't think AI art is going to or even tries to replace art as a creative pursuit. If anything it's more likely to replace certain photography related jobs.

Currently the main use cases are

• Generating stock photos
• Generating texture maps
• Generating concept art

None of these things really care about intent, you could argue concept art does, but a lot of the time it's just there to set a vibe/direction/theme. All of the above will still replace jobs but not the typical everyday artists jobs, maybe stock or texture photographers though.
