Ok, I had some time on my hands so I decided to test out My
AI Scientist Tag, with the Great General and Great Agriculturalist AI Civs
I unfortunately picked my custom Civs, forgetting that 2 were based on the Washington AI and the other was based on a modified Bismarck!

Doh!
the two modified Washington AI Civs are what me and my bro use so I forgot to edit the AI tags (since we would be both using it not the AI) therefore acted similar

whoops!
the modified Bismarck was modifed different (more aggressive) than the "vanilla" AI so that's cool I could see how my new AI tags would play
I am playing Normal Speed
I stopped testing at the year 2720 BC
however I have positive preliminary results!
so far here is the normal pattern:
1) they all start the golden age with the GG
2) then they build the Military Academy
3) then they make a great specialist (for the washingtons AI they usually made it in the capitol... Bismarck AI started in capitol then moved great specialists in other cities besides capitol
I forgot to include Great Agriculturalists at first!
when I added them... they followed the same pattern
1) started golden age (if possible)
2) built grange
3) great specialist in capitol
AI responses:
Washingtons (Both that is) AI would cram GG and GAg as great specialist in Capitol even if other cities did not have grange or mil. academy
when there were alot of great specialist in capitol they would finally branch out to other cities... either making the missing grange or mil academy...
or making great specialists in that city
Bismarck was alittle different...
after making the mil. academy and grange in the Capitol...he made 2 GG great specialists in the Capitol
then, unlike the washington clones, he spread his GG and GAg around to add the cities adding grange and mil academies...then great specialists to the city
Notes:
I got kinda bored testing so I save the beta testing and gave this report
I dont know if I will start a new game with more diverse civilizations to see different AI response
I did not see any war yet (dont know if it was too early) so I could not see if any GG were in action so I might continue with this game to see if war develops and to see how the GG are used
there were a couple of quirks that I did observe:
sometimes a civ would save a GG or GAg then use it as a great specialist in the city, or make a special building after one or two turns
sometimes a civ would save a GG or GAg and wait till a new city is built and send the GG or GAg to make the special building there (this is not a bad thing... just something a little different from there normal patterns)
sometimes a civ would exchange GG/GAg within their cities:
example:
City #1 has a GG and City #2 has a GG
City #1 would send his GG to City #2 and City #2 would send his GG to City #1!
then both cities would use the GG as a sp building or Gr Specialist
weird huh?
I only saw one case where the AI used a regular City specialist of Sergeant (but none as of yet of Farmer.... though it maybe too early to because of small pop and pop growth)
I forgot to observe if any used to "hurry/discover" tech option.... but if they follow the AI Scientist I dont see why they would not do it... (they used the other GP options)
Verdict:
Still early to tell (especially the war aspect and upgrades)
but it looks goooooooood!
the AI is utilizing GG/GAg instead of destroying it or just letting it sit in the city and do nothing (but waste resources) *yay!*
It good to see the AI use them as specialists/great specialist/special buildings
I will continue testing.... but I still gotta test in MP and I think this weekend I think I might try to merge part of TheLopez's Great Doctor in this mod! (and that may take some time)
Faithfully reporting and beta testing
I'll report back soon
