Talk about computers being as smart as people is getting louder. This comes with the release of new advanced AI language systems like GPT-4 from OpenAI. A recent study by a group of Microsoft researchers says GPT-4 is starting to show human-like thinking. This is seen as a big step toward "artificial general intelligence" (AGI). But, not everyone agrees. Some experts in AI say it will still take many more years to reach AGI. Some even think it might be impossible.
