Nice article on Meshtastic. The problem is that, like anything, the actual distance is a lot more dependent on line of sight and the actual mesh existing. Which means we’d need a LOT more people to adopt these and put up repeaters for them to be useful. Which is doable, but not cheap.

Companies are starting to manufacture repeaters and they are not that expensive. You can get one for about 100 Federal Reserve Notes.

At that point, given the extremely small bandwidth, we might as well just use a massive wifi, everyone already has the required hardware for that instead of producing more trash for a pretty much non-existing use case.

Why not just add networking capabilities or a SIM card?

You can't expect me not to reinvent the wheel.
As we post on Lemmy, which is a reinvention of a reinvention of a reinvention of Usenet from 1979.

I thought Al Gore invented the internet in the ‘90’s.

This has much greater range compared to wifi

You can have one or the other. If you choose high bandwidth, you're going to get very short distance because you can't do serious error correction, etc. If you choose long range, you're going to get low bandwidth because you need to include error correction, etc. In the transmissions.

Sucks you can’t charge it and have to instead go to a central bank to exchange minted coins for notes that you can exchange for the commodity that is the radio.

Ok, rant time!!!!
I worked for Vint Cerf back in the early 90's. I became aware of the politics around it when Al Gore pushed for funding so the Internet could grow into something bigger than a University/Military communication system. Rush Limbaugh was on the radio daily railing against Al Gore's Boondoggle. Clinton/Gore secured funding and the Internet exploded in use.
During the 1999 Presidential election, Republicans took Al Gore's greatest political accomplishment, getting Congress to fund the creation of the Internet, and made it a joke.

Well, back then it was a bunch of tubes.

I wonder how much you could Jerry rig up Wimax for these days. That's like 30 miles of range. I remember thinking if I was only going within a 15 mile area of my place it would have been cool, but prices 10 years ago immediately made it a no.
Edit: like it sounds dumb, but what prevents someone from picking up a used Wimax base station, putting it as an uplink from their router, then using a Wimax card to receive it? Could even maybe just rig up a small rechargable wifi box, that received the Wimax signal, then rebroadcasts it back out as wifi using your home network name/password. So anywhere near your home the antenna would just pick it up and rebroadcast, maybe just hook it to your cigarette lighter to charge so anytime your in the car it's on. I assume most people would find it easier/cheaper to just buy a cellular card.. haha. But hypothetically, I am curious what would make it not work

Some people already are
But the point of LoRa is in the name, long range. Wifi barely reaches outside my house. Also a WiFi mesh is dependent on a variety of complicated and proprietary networks and systems while meshtastic is entirely independent.

Funny thing about Wi-Fi, it overlaps with an Amateur radio band (the 2.4GHz spec does) and so hams are allowed to run Wi-Fi with no encryption but a tremendous amount of power and high gain antennas on like the highest channels.

Have a look at meshmap.net. That shows people who have voluntarily put themselves on a map.
Although it can be a serious underestimation, for example in my area, I'm the only one who lists myself on the map, but there are about 10 other nodes that don't
Edit: Also, the number of nodes on MeshMap has pretty much doubled in six months since I started playing with it.

I always thought these were more like walkie talkies for messaging than telephones that you can call anyone.
Like it would be good if cell serivce goes down.

At the very least fathered the internet we know today.

Eisenhower gets credit for building the Interstate Highway system despite not pouring any concrete.
