Excellent point.
While all the generic AI pics are great in itself, for me it is even more fantastic for giving the opportunity and possibility to illustrate celebrities that I already find attractive (and that I fap off to regularly anyway) in hairlengths and hairstyles beyond their norm, which are arousing to me. This makes them so much more desirable. Combine the hair look in a scenario that is arousing for me (mile high, secretary, mild bondage, and of course, hairjobs!), and AI is truly a magic formula.
AI pics are indeed not real (as many have opined here), and may not be perfect, but it is good enough for my mind to fill in the gaps.
I hope I do not offend anypne with this post.
