Looks professionally done in a lot of cases.
Easily at first glance. The AI is just having a bit of trouble with the symbols. An AI generated art and with just a few touch ups by a graphics designer(to fix the weird symbols) then there's an 80%+ chance I wouldn't be able to differentiate it from human art.
Yes some of the logo attempts look under developed to a point that it you didnt know the
artwork was Bitcoin themed you wouldnt get it.
Then in other cases the logo looks enough developed that it is identifiable but looks like
an "ancient" form of the logo and looks like it suits the mood of the "art".
If you compare the life of a person studying fine art who goes through the different media
like watercolour, oil, acrylic, pastels, graphite etc. and the various techniques and different
surfaces over a number of years and then specialises in a particular field honing their style
and individualism and compare that to a computer which can knock something like the above
out in a short space of time, there is definitely a value in one but what about the other?
