On a more serious note, I do agree with you that memory and self-excitation seem like they are the last push thats needed to get to something more akin to "AGI". But I don't think that Rubicon will be crossed with plugins.

"We show that transformer-based large language models are computationally universal when augmented with an external memory. Any deterministic language model that conditions on strings of bounded length is equivalent to a finite automaton, hence computationally limited. However, augmenting such models with a read-write memory creates the possibility of processing arbitrarily large inputs and, potentially, simulating any algorithm."
