As a whole I believe the essay is a great work, but I believe you could have expanded and gone into greater detail with several points you raised. The first two paragraphs serve as a good introduction into the topic and present how bots work nowadays.
Now, as you reach the 3rd paragraph with comparing human brain processes with those of a computer. Now while I do agree with what was said in the 3rd paragraph, you make a "mistake" in the 4th paragraph when you say "Computers may be able to immitate human behaviour through their programming, but they will never “think” like a human being.". As long as a computer runs a fixed program that we created and follows our commands it will never really be able to be conscious. It will never be able to really learn, develop or evolve into a conscious / "thinking" thing since it will always work on a set of rules and logical operations we set.
But if we were to make a computer of amazing capabilities and created a program base that would function as one's subconscious and and that would feed information to the computer whilst also having a "conscious" programming part that would allow for self-alteration (so that the program can modify itself as it sees fit) you would only be limiting the computer to what his hardware can do, much like we are limited to what our neurons can do. Think of it this way (assume that we have reached the impossible as far as hardware goes): you have a real human brain in a vat. Now you copy the brain's exact structure, connections, neural actions into a counterpart machine connected to whatever the brain in the vat is connected to. If you would really manage to copy that brain and if the hardware would allow for neuron simulation you would have created a conscious being. It would not be limited to your preprogrammed rules and operations, it would, just like a human or animal, be able to create new "neural pathways" etc.
Meh, I explain way better when I'm not limited to typing out my thoughts
Another point that I have to disagree with is the one you made about a human's "emotions, morality, and personal values". Of those only one is biologically predetermined - basic emotions. Morality and values are a product of the culture where you're brought up. But, as I said, if we would be able to recreate something of the brain's complexity and create the parts not under our conscious control, we could in a sense imitate even emotions.
I'll go into detail later, I don't really have time to write an essay now
