Which are the main things Lain predict? Could someone refresh my memory?
From what I remember (spoilery):
1. That the virtual, online representation of a person will be difficult for many onlookers to distinguish from the real person. Like a bot that can act exactly like ahill (oh god, jk).
2. That the online representation will be become sentient or behave in a way that's indistinguishable from sentience.
3. The online representation will behave differently and exhibit thoughts different to its parent person to an extent that at least the parent person will notice, maybe due to the parent person only presenting certain parts of their self to the internet or presenting aspects of their self in different proportions compared to how they present to others offline or compared to how they present their self to themselves in their own mind or due to sentience or due to interacting with other online representations and reprogramming itself based on those interactions, or some combination of multiple of these.
3. That the virtual life will become prioritised over the physical life, to the detriment of the physical life. Lain's physical body starts to waste away because of her addiction to visiting the virtual world. And I think the girl killed herself in part because she thought her internet self can live on her behalf, so she doesn't need to keep living? Maybe she was already depressed and suicidal and that pushed her over or maybe her internet self being so good at mimicking her gave her an existential crisis that led to suicidality.
4. That billions of human minds, either directly or via their personas hosted on the internet, will be connected to each other to create one giant hivemind that can think for itself by combining its constituent minds.
