Hi, Let me hop right to the question below:

In fact, it's been done at least four times, with opencog, in the last 10-15 years. Each distinct effort was a success .. or failure, depending on how you define success and failure. I certainly got a lot out of it. Whether it's herculean or not depends on your abilities. It's not hard to whip up something minimal in not too much time, say in a month. What you'll have at the end of that is a toy, a curiosity, and the unanswered question of "what does it take to do better than this?" > What are some milestones and topics/resources I may need to investigate > further work towards this pet project if it's doable? > For language, you would need to understand link-grammar. You'd need to read the original papers on it, as a start. Code that dumps link-grammar output into the atomspace is here: https://github.com/opencog/lg-atomese It works, its maintained, I think it's "bug-free" but if not I'll fix them. What you do with things after that .. well, you're on your own. One of the more recent attempts to build a talking robot is the R2L system (relex2logic) but I don't really recommend it. You can study it to get a glimmer of how it worked, and learn from that, but I would discourage further development on it. If you are into robots, then some early versions of the Hanson Robotics robot (named "Eva") can be found in assorted git repos, but it would take a lot of git archeology to recreate a working version. But this could be fun. (The robot itself is a Blender model. It can "see" via your webcam, and actually track you!) There's assorted proofs-of-concept of things working at higher levels of abstraction, but converting those into something more than a proof-of-concept is .. well, the question would be, why? There's a lot of things one could do; there's a lot of things that have been tried. It's like climbing a mountain in the mists: a lot of possibilities, and a lot of confusion. > I'm currently working through the opencog hands on sections to get a feel > for things. > Opencog is a bag of parts. Some parts work well. Some are obsolete. Some code is good, some code is bad. Some ideas are good, some ideas didn't work very well. At any rate, its not one coherent whole.
