Simulating the whole brain as an alternative way to achieve AGI

We have all seen the current attention,and even hype,on big models and artificial general intelligence(AGl).Indeed,many colleagues are arguing that we have achieved AGl with the current version of ChatGPT.Really?Looking back,it is not surprising to have a machine,even a normal calculator,which can outperform us.For example,a calculator can easily beat most of us on the multiplication of two large numbers with its speed,while a basic laptop can store many books,but humans have far weaker means of recall.So it is something that we have already got used to,that man-made machines can perform certain tasks far betterthan us.
