Are kb programs becoming sophisticated?

[LieoUhlerredyh]

Are kb programs such as "dfw" and "the giant" considered too simplistic? How do these programs compare to more advanced knowledge base systems in terms of complexity, capabilities, and performance? What are the specific limitations of these programs, and how do they fare in handling complex tasks or nuanced inquiries compared to more sophisticated knowledge base solutions? Additionally, are there any notable strengths or unique aspects of these simpler kb programs that make them suitable for certain use cases despite their apparent simplicity?
