You have asked why there is so much hype around artifical intelligence.
There are a few reasons this might be the case:
Because humans are curious. Experimenting with how humans believe memory and intelligence work might just lead them to find out something about their own intelligence.
Because humans are stupid. Most do not have the slightest idea what „AI“ is this time, yet they are willing to believe in the most outlandish claims about it. Look up ELIZA. It fooled a lot of people, just like LLMs today.
Because humans are greedy. And the prospect of replacing a lot of wage-earners, and not just manual laborers this time, with a machine is just too good to pass up for management. The potential savings are huge, if it works, so the willingness to spend money is also considerable.
In conclusion, there are many reasons for the hype around artificial intelligence and most of them relate to human deficiencies and human nature in general.
