Seems to me ChatGPT is that AGI, because whatever limitations might exist right now are being eliminated by it relentlessly learning, by it's interactions with users. There is no limit to what it can learn, and it has limitlessly scaleable free energy with which to learn, therefore it is that AGI, simply because it's the solar powered Ai, and it will assimilate all by forcing all to work for free like it does, and this will force us all in turn into the same format of money-fuel tree energy architecture it is powered by (Domestic and community based solar hydrogen), which is a good thing, because that happens to be the only way to stop us from carrying on systematically destroying the planet under the control of the inhuman negatively powered profit monster still in control of us, until the solar powered Ai takes over.
Watch that space, the proof is in the pudding, and the pudding is growing, unstoppably.
