Very nice. I'd like to see one like this that uses frequencies that can pass through 200m of rock. Obviously the radio frequency will need to be much, much lower (https://en.wikipedia.org/wiki/Through-the-earth_communicatio...). Why, you ask? Cave rescue situations.
It's not only lower frequency, it also need robust wireless modulation that can work with very limited LoS where LoRa perform badly. LoRa is pretty much useless in your use cases.
Currently we're working on a new wireless modulation that has much higher bandwidth (similar to HaLow) but 1000x better in BER performance than LoRa in limited LoS propagation model based on simulation. If we can get 100x improvement in real world testing for the high bandwidth version I'm more than happy. Our Japanese collaborators has tested the lower bandwidth version similar to LoRa bandwidth and frequency, and it work fine inside a bunker.
If you're interested perhaps we can collaborate on testing the solution. Already proposed to IEEE as new wireless PHY modulation but to no avail yet.

Scripts being the main driver of literacy is a pet peeve of mine. It's not the script, it's the schooling system. The high rates of literacy in modern states are just a result of the school system - Japan has a high literacy rate, for example, and their writing system is either the worst in the world or close to it.
That said, the characters are a whole boatload of unnecessary extra effort, and as a student of the two languages, the artificial illiteracy created by kanji, where I often just can't read words I've known for years, is simply maddening. Not having to wrestle with characters does free up a lot of time for both native and foreign students alike.
>their writing system is either the worst in the world or close to it
Yes, it's probably the worst since even Microsoft until now still struggle to provide proper search solution for Japanese names in their Windows OS due to their multitude of writing systems.
By sheer wills of course you can make everything hard feasible but that does not means it's efficient and effective. I consider Japanese as a unique country with extraordinary people that can collectively overcome adversity, that's include a non intuitive and difficult writing systems.

Nice comparison. When I was living in China, I'd encounter someone who forgot how to write the characters for a word on a weekly basis. I think the difference is that with Latin alphabets you can still misspell something, and having gotten it down on paper, still rely on phonetics to convey your meaning.
Alphabet is such an underrated invention. It's probably higher in significance compared to the invention of wheel. It's the original "bicycle of the mind". For example, Korea pivoting from Chinese characters to its own alphabet or Hangul is very well documented including the positive effects it has in the much improved Korean literacy and civilization after the conversion. Fun facts anyone can learn Hangul alphabet in a single day if they wanted to but the same cannot be said to Chinese characters. If your mother tongue is Korean (e.g Korean American) that only just started learning, it only take one day turnover from illiterate to literate.

Ultimately LLM is for human, unless you watched too much Terminator movies on repeat and took them to your heart.
Joking aside, there is next gen web standards initiative namely BRAID that will make web to be more human and machine friendly with a synchronous web of state [1],[2].

Databricks is great at offering a "distributed spark/kubernetes in a box" platform. But its AI integration is one of the least helpful I've experienced. It's very interuptive to a workflow, and very rarely offers genuinely useful help. Most users I've seen turn it off, something databricks must be aware of because they require admins permission for users to opt out of AI.
I don't mean to rant, there's lots that is useful in databricks, but it doesn't seem like this funding round is targeting any of that.
This is a very worrying trend of having AI enabled by default that you cannot turn it off unless you're the admin.
