I'm claiming that strong AI is a very active field of research. Frankly, all the "models" you've listed aren't very interesting, relative to what's really going on in AI research, so, no, I am not making any claims as to whether people have tried those particular approaches.
If you're really interested in the field, you might start with the obvious:

It's just strange that you're so long-winded about this one obscure niche within the AI field, while true AI research has somehow passed you by entirely unnoticed. If you'll take the time even go through the Wikipedia article, you'll see that there are entire "institutes" (more than one) that are well funded and making real progress toward strong AI. There's also a very brief mention of this "Numenta" that you're talking about.
What's holding AI back isn't that we just haven't gotten around to it yet. If someone in the AI community had an approach to strong AI that was worth a shit, we'd have strong AI right now.
