AFAIK, that was the stuff Goertzel was doing as Director of Research. Now that he isn't around anymore, those things were dropped.
Pretty much the whole "practical experimentation" angle is, again AFAIK, considered too unsafe by the people currently running things at SIAI. At least that's what I was told during my Visiting Fellow time.
considered too unsafe
I expect improving on state of the art in practical AI is also almost totally useless for figuring out a way towards FAI, so "unsafe" is almost beside the point (except that making things worse while not making them better is not a good plan).
One of the reasons that I am skeptical of contributing money to the SIAI is that I simply don't know what they would do with more money. The SIAI currently seems to be viable. Another reason is that I believe that an empirical approach is required, that we need to learn more about the nature of intelligence before we can even attempt to solve something like friendly AI.
I bring this up because I just came across an old post (2007) on the SIAI blog:
Some questions:
I also have some questions regarding the hiring of experts. Is there a way to figure out what exactly the current crew is working on in terms of friendly AI research? Peter de Blanc seems to be the only person who has done some actual work related to artificial intelligence.
I am aware that preparatory groundwork has to be done and capital has to be raised. But why is there no timeline? Why is there no progress report? What is missing for the SIAI to actually start working on friendly AI? The Singularity Institute is 10 years old, what is planned for the decade ahead?
