alt Hacker News>To be perfectly upfront with you, this post will be glossing over many Meshtastic and MeshCore features, because I feel they are both non-serious solutions compared to Reticulum for reasons I will explain later on in this post.
Yeah, that's the general feel I get every time I poke into Mesh*. Neat radio tech, fun toy to find other nearby nerds, instantly-obvious problems that are fatal to growing beyond being that toy (or small specialized personal nets, where it's totally fine). They feel more like a tech demo than anything actually intended to survive.
Which is fine, you kinda need that to start out, and they do work today. Just... hard to get excited about.

That weakness is a strength.
Everyone you meet on a mesh is a real breathing nerd, who due to proximity has a lot in common with you. They are not trying to influence you or sell you anything
How many places like that are left?
I'm right now anchored at an atoll in the Tuamotus, French Polynesia. 3/10 boats anchored here have Meshtastic.
The inherent limitations of free spectrum mesh technologies will never lend itself to a replacement for the Internet so will always largely exist in niches. Niches like personal nets, local nerd networks, or emergency response (tho actual first responders are not the most eager to try this stuff based on my experiences in the community.) All of this can be a feature or a bug depending on whom you ask.
On the mesh in Toronto with meshcore we have regular communication that reach all the way to Buffalo. We are past the « toy » stage, it’s truly impressive.
It's pretty hard to imagine anyone "getting serious" with these tiny radios designed for reading gas meters and weather stations and using that to build some kind of off-grid alternate Internet.
I'd almost have more faith on dragging out all the old acoustic coupler modems and building a city-wide string-and-tin-can telephone network.
Of course they are not useless. My hiking/camping friends put together a fun orienteering game which used Meshtastic to do live GPS tracking. Worked great for that. But a country spanning meshternet it is not.
I don't think it needs to be though. There are plenty of things to explore using these things at the local 1-10 km scale.
To be fair it is already a miracle that there is enough Metastatic in my area that I can (sometimes/rarely) send a message between my home and work!
*disclaimer that I am coming off a recent disillusionment with Meshtastic. I thought it would be fun to make a single raspberry pi image with all the dev tools on it to do some off-grid dev/maintenance work if you were to treat this seriously and pretend the main internet is down. That moment came when I tried to compile something and the Pi ran out of memory. Really? I need more than 1GB RAM to compile something used to send short text messages?! That's nuts!
I think meshes do work extremely well in practice, and are quite resilient with regards to errors, and load balancing, and they get better as you add more nodes.
I think it's perfectly feasible for a small neighborhood of regular people to have internet shared over a wireless mesh network, yielding experience comparable to standard approaches.
