No one knows what AGI is. There isn't going to be some switch that flips to take us from AI to AGI. These tools we have today will just keep getting incrementally better, and some new ones will pop up, and at some point we'll have to stop and say "yeah, this is good enough to qualify". And everyone will have their own opinion on what that point is. Plenty of people even think that we are there today, and there's nothing stopping Google or OpenAI from claiming it if they want.
And you can say the exact same for consciousness, sentience, self-awareness etc.
