And what do you expect them to conclude if even a professional AGI researcher, who has been a member of the SIAI, does write the following:

Every AGI research I know can see that. The only people I know who think that an early-stage, toddler-level AGI has a meaningful chance of somehow self-modifying its way up to massive superhuman intelligence -- are people associated with SIAI.

Is that really the idea? My impression is that the SIAI think machines without morals are dangerous, and that until there is more machine morality research, it would be "nice" if progress in machine intelligence was globally slowed down. If you believe that, then any progress - including constructing machine toddlers - could easily seem rather negative.
