In the late aughts and early 2010s I and a few other people came up with the `darknet plan` aka `project meshnet` which was a subreddit and adjacent communities dedicated to creating a completely parallel internet using 802.11s mesh networks akin to the Athens and NYC meshes that span a huge portion of those metros.

The movement eventually got coopted by the CJDNS project and its fans. Instead of a completely separate internet they were advocating more of an overlay on top of the existing internet (because that didn't require solving interurban/intercontinental backhaul), which to my mind addresses essentially none of the problems we set out to solve, so I eventually lost interest.

But today we have things like LoRa and a greater hacker community around the ISM bands, which might be just what's needed. I have hope one day we can achieve global interconnectivity without rent-seeking ISPs.
