Eurisko is more legend than history, at this point. As far as I know, the source code was never available to anyone except Lenat, and most of the claims about how effective it was at the beginning were sourced directly from Lenat, as well. The fact that we've never seen anything similarly small and effective (and that Lenat abandoned the entire approach in favor of Cyc) makes me wonder how much of what Eurisko is reported to have done is exaggeration.

Your scenario with the Em that's copiable and ten times faster than a human is exactly what I started this with. :)
