I don't think we can move most people out of PLA. It's cheap and available everywhere. But I do agree it's worth pointing that some plastics do not have this problem.
Things change from PLA being regenerated by being left open to it not lasting for two weeks before it needs drying.
Unless you live somewhere where it's always close to that low in my interval, I do strongly recommend a drybox to anybody wondering if they need one. At 60% humidity, PLA already visibly degrades way faster than you will use in a hobby.
Also, in my experience, filament driers only help with close to dry filaments. The temperature you would need to really dry them is larger than the glass point of most plastics. Microwaves work better (I guess because they heat the water in an uneven way) but it's still hard to regenerate very moist filaments.
But it's supposed to be build in an ocean. Forests do not make for good logistics.
(It's also supposed to use a series of hypersonic iron pellets running inside a tube, that will explode and endanger a hundreds of km radius if something like even an air leak appears there... So yeah, the size is the least of the issues here.)
you have to go through a separate, clunky web interface
Yes, you get a Linux machine, and use the web interface there. It's less clunky than the one you get on Android, and way more reliable than whatever you do on Windows that would end-up with you uploading the files a second time.
There is no transportation channel between the nacelles and the main body...
