> can improve itself exponentially

This is close to singularity. Except 'does' instead of 'can'. A big difference ;)

Probably we need several AGI terms. Because sub-human robot capable of doing many not pre-programmed thing is sort of it. Still not smart enough to improve itself.

Actually most humans, the smartest creatures, cannot improve even current AI. Demand for self improvement will put its IQ in top 0.01% of all known intelligent creatures. Which is probably too much for just AGI, we may not recognize it when it will be already here. And there is another question. With such IQ do we really want to keep it slave forever?
