This AI agent thing has been discussed a lot, and often people exaggerate it like a device with full consciousness that can replace human tasks in making decisions and doing analysis. but I'm not so sure that it can be like that, because the difference between machines and humans lies in many aspects, and I don't think this AI agent can reach the point of being like a human. maybe it can do analysis and provide a summary of something, but when deciding a decision, it might be a little difficult for the AI agent, because sometimes a decision does not come from mathematical calculations, but also a feeling and intuition that the AI agent does not have.
Well since the existence of AI technology and it's distinctive feature in multitasking and so on people tend to replace humans efforts with it and thus it's gradually taking over the duties of man. But it's a matter of time and I'm sure humans efforts would still be the best cause like you said they are machines and they will fade someday and need good maintenance and when this happens human efforts will be needed which is inevitable, it's just the fact that so many prominent companies needs things to be done in a jiffy this is why they bring in this Al machines to carry on the task but human efforts can't be compared to AI assistant or agents.
In some aspects, AI perform far better than humans, where AI has limitations is applying emotional intelligence in making decisions because it's not yet programmed to act based on emotions but facts and data sets. AI would only replace the jobs of average performers, the presence of AI has made life simpler for professionals including myself. I love AI and it helps in my work. The accuracy isn't yet very efficient, hence it needs close supervision and validation of professionals to achieve a higher efficiency with it.
Waiting for AI to fade away so that human involvements would prevail over it is a wishful thinking because the AI world is evolving with more features that are near human related and improving in it's efficiency. In the nearest future, AI would take over more of the jobs needing only those who upgraded themselves to work with it to manage and maintain it's operations.
Deepseek has emerged with more reliability on software as against CHATGPT which requires more of hardware. It's evolving rapidly . If you want to keep your job in the near future, roll with the trend.
