My answer is "no". Just because the initial pruning has to quickly find a balance between efficiency, speed and reliability vs. width, breadth of input/processing of new data. The 15,000 synapses/neuron that we have grown at around age 3 must be cut in half... After that, plasticity is still there and possibly can be boosted somewhat but not to the initial level. We have enough potential for plasticity left to learn and discover until an advanced age but it will require more work (i.e. expense of energy) and more sustained stimulation because the brain now needs to be "convinced" that it's going to be useful (i.e. rewarding) which our robotic lives doesn’t really allow, let alone promotes.
