The whole question of EKI One is somewhat academic now as Artificial Technology no longer exist having been bought out by the Masa Group and their team dismantled. They retained some of the key developers and company founders to integrate aspects of it's technology into the Masa product range. Although the product is still for sale, EKI One is no longer being developed or supported and hasn't been for some time.
This I believe shows a complete lack of understanding of what the EKI One product is capable of and the exceptionally good tool sets it contains. I'm sorry to say that your blatant disregard for other software developers products and achievements never ceases to amaze me!
Absolutely, one of the most powerful mechanisms for aiding AI implementation. But like most mechanisms, once you start to build complexity you need to add tools to manage it effectively.
I agree that state machines and steering are almost a prerequisite for AI suites these days given that you already have path finding. Interestingly, EKI One allowed you to define and configure your own perceptions, the only one hard coded into the product was sight. So perception was limited only by your imagination and ability to script them.
