The shelves are stocked the same way they are picked, by having the robot travel to a station where a human places the items on the shelves. One way to organize the warehouse would be to put the replenishment/put away stations near the incoming goods (e.g. receiving area) with the picking stations on the opposite side. not sure if this is how Amazon is configured or not.

Just one example of many of the need to properly model the dendritic computation is the hippocampal CA1 pyramidal neurons performing 2 different computations depending on the spatial distribution of the incoming signal (and level of synchrony). Either it performs input strength encoding or feature detection. You can't ignore this and end up computing the same thing, your end result will be different.

Well, if we consider the example of object recognition happening in dendrites of human visual system, that requires a neural network all by itself to emulate. It's absolutely doable, but there is a huge difference between integrate and fire and a non-linear NN style mapping of input to output. There are other examples of dendritic signal processing which all point to neural computation really being a level below the neuron, each neuron is a network in it's own right. So, instead of 302 neurons, to properly emulate, we may need 302 * 10,000 computing nodes ("neurons").

Researchers are finding that those dendritic computations are frequently very important. One example is that object recognition happens in the dendrites in human visual system. Another example is that backwards spiking in the dendrites is a key part of learning. Maybe you can emulate the dynamic learning algorithm but I seriously doubt they figured it out and are emulating it, which means the system is not dynamically adjusting the same way the worm does.

They did not emulate the functionality of a neuron. If you read up on the subject you will find that the neuron is a network all by itself with spikes moving forward and backward, local spikes on the dendrites, the dendritic tree performing multiple simultaneous linear and non-linear computations, etc. etc. etc. They used an extremely simplistic formula that completely skips over these computations that have been shown to be very important for the proper functioning of the neuron.
