I think that in this case, an organization's self-improvement to the issue tracker source code recursively 'fuels' other improvements to the organization's cognition.

Yes, it can fuel improvement. But not to the same level that an AGI that is foom-ing would. See this thread for details: http://lesswrong.com/lw/g3m/intelligence_explosion_in_organizations_or_why_im/85zw

I think we may be arguing over an issue of semantics. I agree with you substantively that general intelligence is about adaptability, gaining and losing skills as needed.

My point in the OP was that organizations and the hypothetical AGI have comparable kinds of intelligence, so we can think about them as comparable superintelligences.

I agree that organizations may be seen as similar to an AGI that has supra-human intelligence in many ways, but not in their ability to self modify.
