The more people will be spending their time in the Metaverse that is how our cultural heritage will be gradually dying.

You are right . I fear people would forget that the real world is outside the metaverse .

suffering from schizophrenic symptoms are of risk.

You are right . Even those who don't have schizophrenia or normal , they have chances of getting addicted to the games etc and addiction is a form of mental illness . Morever , physical health would also be compromised as people would spent hours playing games or watching movies without caring for health ofmr time .

Thanks for sharing your understanding of metaverse.
