I think he means node based decision networks of AIs contrast what behaviorism is commonly limited to. The integration of psychology and biochemistry would pick up where behaviorism leaves off, if we assume that chemical components of our mind such as predispositions of dopamine and serotonin are what control our actions. Behaviorism is a level of analysis that doesn't really tell us much but is cool and fun as fuck to bask in.
The problem always is someone thinking they have acquired apex knowledge and then poorly implementing it without the scaffolding to build something from it. The idea of conditioning has lead to a gross amount of dehumanization because it promises a brute force way to make a human work a certain way, reducing us to automatons that can be bred and trained like a dog, bird, or horse. (which is fucked too tbh)

If you have reason to believe that you have a hefty amount of psychological knowledge, I would recommend you study what has shaped ours, and in fact, everything's psychology indefinitely, and that is the environment. Ecology is very underrated, and honestly very fucking hard. You don't have to be limited to just forest's and and deserts either, there are various ecological studies and books on many contemporary environments.
