Emulation of human thinking in other media will be constrained by cost.
Technology assets generally decline in price as more efficient means of production and distribution become available (i.e. cloud) and the cost of technology components becomes more commoditized.
I will extend that further to claim that the only way to get a very human-like thought process is to run the computation on very human-like wet tissue.
I think wetware (or human-like wet tissue) needs to be created first, before any judgement can be made about it’s costs.
