It's true that making an AGI, given current software technology, is a big
pain, and it takes a long time to get from vision to implementation.
I agree that better software tools would help make the process a lot easier,
even though I have a feeling your vision of better software tools is a bit
However, I have chosen to focus on AGI itself rather than on building better
tools, because I've judged that given my limited resources, I'll probably
get to AGI faster via focusing on AGI than via focusing on tools first.
While tools work is conceptually easier than AGI work by far, it still
requires a lot of thought and a lot of manpower.
I would be more interested in your tools ideas if they were presented in a
more concrete way.
