Nashville Number system

[Triple-o]

Years ago I  heard someone talking about the “Nashville Number System” . I was just starting to learn guitar so I never looked  into it. Recently he showed up  on my radar so I took a peek. Turns out most players use it in one form  or another…for example  1  4  5 for chords. 

Seems  musicians  started using  “Roman”  numerals  in the 1700 century and  that’s seems to the basis of the system used in Nashville system. About 1950 Neil Matthews came  up with the system. It appears to be used mostly by session musicians, producers and touring bands.

The average guitar player uses it to some degree. Some symbols like diamond shapes and parentheses not so much.  

I was curious what AI would say so I asked  it how C7 b9 b5 would be written in the Nashville numbering system. It said a musician would  often write it has 57b9. 

Edit :the  first time I asked AI it said 5+. Then I recently realized AI isn’t always consistent with it answers so I asked the same question again the morning and got a different response.

Do you think Artificial Intelligence is correct?
