Religion will become popular again and people still start falling for nonsense like ghosts and superstitions. People born after the 80s don't really remember just how batshit crazy people went for misinformation before we had the internet.
We need a new internet without corporate bullshit and some integrity in terms of knowledge. But seeing what happened to the current one, I don't think that will be possible until we kill capitalism.
This is what CB Radios are, and many more people used to have them before cell phones.
People in mountainous areas where a cell phone is useless still do.
