Pluggable AI with Scriptable Objects

Hi guys,

I've been thinking about the best way to implement my next AI system.
I want it to be as modular as possible and this is why I first thought about prefabs and variants, but looking for threads about it I found this tutorial :

https://learn.unity.com/tutorial/5c515373edbc2a001fd5c79d?language=en

It seems pretty nice and I already used SO to build my database, inventories and stuff so I'm not totally stranger to it.

I wanted to know if any of you already implemented it and tried it in your games, if you had problems with it, found it easy to expand, well, any input you could give actually !

Also, if you know other way of building a modulable AI with prefabs/variants, please feel free to elaborate !
