There are several reasons why people might be scared of the idea of a meta-verse.
One reason is the potential loss of privacy and control over one's personal information and online identity within such a world.
The blurring of the lines between what is real and what is virtual within a meta-verse could lead to confusion and disorientation.
Furthermore, the potential for addiction and manipulation of individuals by those who control the meta-verse is also a concern.
The idea of being trapped in a virtual world indefinitely, or having one's consciousness uploaded into a virtual world after death, could be unsettling to some people.
People may also be scared by the potential of how a meta-verse could change the ways we interact with each other, and how it could change the way we perceive reality..
If we will realy catch in this metaverse and think that for example virtual field of known artist is worth of buing and spend a lot of money for it... I don't know what it will be. The same time and money you can spend making and buying things which are in reality and not just in servers.
