The brain and body instead construct time, a cohesive internal one,from the ground up, with nesting oscillators driving the sequence of all functions and behaviors, over long and short time closes.
What we call “thinking” is a filtered layer of it, a slice that the attention spotlight is focussed on, and in humans this process can be turned to cognition over multilayered abstractions, and using language or other symbolic communications to communicate some of the dynamics of this process, and even evoke them in others.
Turing machines, and modern digital computers with their Von Neumann bottleneck, and LLMs are outside of time. They do not experience time. They can check the clock. They can count steps. But they are not active and agentic in time. Till we change that we won’t make machines that “think”. We can certainly make machines that simulate thinking, and that’s often good enough. But make the problem a real time one, with several conflicting verbal streams to parse and respond to serially and LLMs on their own fail catastrophically.
I think so long as the memory-processing divide remains, the simulation has to break apart processes for thinking in a way that’s alright for some cases, but not for others. And this is why we have the jaggedness of LLM intelligence I believe. They do not have internal timekeeping like almost all biological agents do.
