Pardon me for any confusion, I'm often reminded of this quote: "Barbarus hic ego sum, quia non intelligor illis." I'm new to all of this, but still humbly learning and building.
If modern machine learning models are better for every application, then that's most likely what we'll support. I think symbolic AI still holds some merit when thinking about how to interact with traditional physical interfaces, no? There seems to be a complement in the methods when considering a full stack thinking and acting approach, but perhaps I'm being naive.
For example, if I'm a robot in the world, it would be easy for me to access interface knowledge, and how I could interact with it to complete my task, without needing to reason what the interface does or is. This gives me a basic understanding or knowledge base. Now if there is a higher level method of thinking that produces ingenuity, and as a result a more efficient method for solving a known problem, then I assert more modern techniques can be used to adjust older symbolic representations.
I'm just imagining how an android/autonomous agent would need to operate in the real world, perhaps akin to how we might perceive and function within it, a posse ad esse.
Also I use 'agents' because I am going back through older research and it seems to fit the description of the entities involved (software, hardware, robots, devices, people). I don't see any reason for some of the vocabulary or terms to have fallen out of favor.
In a world of autonomous intelligent multi-agent systems, there is a market for knowledge representation about the world, how to complete tasks, as well as higher level thinking/reasoning functions, et cetera.
