That's why consciousness is "magical," still. If neurons ultra-basically do IF logic, how does that become consciousness?
And the same with memory. It can seem to boil down to one memory cell reacting to a specific input. So the idea is called "the grandmother cell." Is there just 1 cell that holds the memory of your grandmother? If that one cell gets damaged/dies, do you lose memory of your grandmother?
And ultimately, if thinking is just IF logic, does that mean every decision and thought is predetermined and can be computed, given a big enough computer and the all the exact starting values?
