Right now, for most, our Internet is pretty much delivered from centralized sources. This has meant a lot of resources put into centralized approaches like giant fiber lines, server farms, etc - and this approach has its place.
At this point, we have tech that can let people create nice custom routing hw for less than $100, SW helping everything mesh-up, citizens launching satellites, etc+many areas which have already implemented & more working on local Internet type options at to allow access to all.
This can seem intimidating. Why do this?
Many have done this b/c of pricing of available options - but also, while meshnets are smaller now, as meshes build, they can mesh w/ other meshes + In working this, we the people can better control everything from pricing/accessibility> security/redundancy>personal data. We can better respond to emergent issues with more dynamism, etc. Our implementations can be what limits our benefits - rather than top down authorities' choices for us.
