It's funny how one can write a whole article full of details and yet not see that it logically collapses at a very basic, foundational understanding of the topic.

Chat GPT has no model of the world it operates in, it does not "understand" what it says, you absolutely cannot evolve that into AGI.

You can, however, have a very smart ai systems based on it that would accelerate human progress across multiple domains. Or you can fake it and make it feel as if it understands the context to make the user experience better but functionality it would not work, it's an "expert" type of an ai.

AGI by 2025 is possible, but chat GPT is a sign of overall industry progress not progress towards AGI necessarily, if we were able to have an AI that acted as a dog with all the consequences like ability to train it with voice and gesture commands, teaching it to solve a dynamic puzzle like managing a bunch of sheep in a field and then have it perform those tasks and learn to do better over time - that would be a very clear sign of progress to AGI and we do have some projects around that, chat GPT is not one of them.
