As Synchro said, your asking the wrong way, they don't generally answer random threads addressed to them, they're busy and don't have a dedicated community manager answering everything as such (plus Lee is technically on holiday at the moment and also stuck in the lockdown in Wales), Lee really only regularly reads official threads like as synchro suggested the beta 3 thread, he will occasionally when he has time have a flick through other threads, but not regularly.
As to your suggestion, if you had been keeping up with the broadcast and other threads on here Lee has addressed that multiple times. The answer for now is no, there will be no behaviour tree or node system for AI and no large changes to AI at the initial release, he has however contemplated adding a visual scripting system at some point in the future, maybe as a DLC, but he's wary about doing so because he doesn't want to just shoe horn in a messy node system, he wants something sleek and neat looking.
