Do those alerts work for foreigners on data-only SIMs?
Unclear. I have a t-mobile e-sim in the phone I was using and that worked for me.

I’m in Niseko (Hokkaido) and had just driven 2.5h through a snowstorm to my hotel, opened door, and put down bags and phone. Weird alarm from my phone (new phone; forgot to disable, which I usually do because where I live abuses the system for a bunch of stupid alerts for chronic issues), looked at it, realized in Japan it is probably real, so I stood in a doorway. Pretty decent sized storm.
If a tsunami affects me on a mountain something would be seriously wrong, so I’m not going to worry.

Couldn't foundational model training (one of the most expensive aspects of AI) be done with spare power?
One $4mm cabinet of GB300 can generate maybe 10-20x the power/hvac cost per hour so it doesn't make sense to ever have it idle. Vs. $100K worth of miners for the same 40KW conditioned or 100KW raw power.

aren't the new huge ai data centers being built without power redundancy/backups, because speed to market is critical?
https://www.mckinsey.com/industries/technology-media-and-tel...
No one I've seen does without at least battery backup/conditioning/etc. Some may have less than 100% redundancy on generators, but that's mainly because some of them are running with e.g. a 200MW grid feed and 20x10MW gensets and ALSO running about 10-15 of the "backup" gensets as prime power. It's possible corners are cut during commissioning (like they use modular structures during buildout of the tilt-up ISO 5 permanent structure), but substanially no one would do this as their long-term design goal.

People have spent $500M for hardware to mine crypto?
I insure like >$3B worth actively I think (which includes some additional power equipment, hvac, etc. below the scale of main site transformers, etc.). If you count former equipment which has been removed from service over the years it is probably about $5-10B for Bitcoin in total? (Not pulling the BDX to look at specific breakdown of miners vs AI)

Hokkaido is by a wide margin my favorite place in the world. If I could easily HQ a tech company there (for global sales; Japan domestic market is stagnant), I would.

Almost all of the larger commercial miners (especially public companies) are looking at this. There are a bunch of issues (I have a conference talk last week at one of the big mining conferences on the topic, and have met with a bunch of miners on this.)
Probably long term the solution will be hybrid — mining gets done using any spare power. AI training generally requires protected power even beyond firm power and few miners have this for their mining operations, and also most of the mining facilities aren’t in the ISO 5 or 6 facilities we (I insure miners and AI) want to see for $500mm worth of mining hardware. Usually the mining companies don’t want to make the upfront capital outlay for these, so a lot of the time they do partnerships where part of their PPA is shared.
I'm definitely interested in these if they work -- both because mosquito elimination (the world's most dangerous animal...) is interesting, and because it's an obvious demo for inexpensive autonomous drones for various terminal effects.

Well, that's a bummer. That said, this does seem the way of the future. We just need to either figure out maintenance robots and/or find a way to keep human crew happy on long, slow voyages across the Pacific.
The rigid aerofoil sails seem more maintenance-free. Some of those are inflatable as well.
